@William Faucher; regarding the issue of disapeearing issue using MRQ: Like you mentioned, by default it forces LOD 0 on everything, but there is secret triangle budget for each instance. If it exceeds that value (likely to happen if you have a big forest), it stops rendering that instance, but still casts shadows (or at least DF Shadows) Two ways aorund it: 1.) In the MRQ setting disable Force LOD0 on Game Overrides. Then you can tweak LOD distance scale command to get the result you have in the editor. 2.) There is a console command foliage.MaxTrianglesToRender which you can increase (not sure about the default value). HOWEVER, increasing this value can drastically increasing rendering time, so I would recommend method 1. Hope this helps, great vid as usual!
AHA, that explains a whole lot. First time I hear about this triangle budget. That's... irritating, wish it was more obvious, or explained, or mentioned somewhere. I'll give this a try and update!
@@WilliamFaucher Agree. I've been rendering large landscapes for some time now but mostly with sequencer. ( no problem there since it doesnt do any overrides so you get what you see). With the introduction of MRQ I've been having the disappearing issue and couldn't find the reason behind it and therefore a solution. Only after submitting a ticket to Unreal Development Network and I managed to get an aswer reagrding the triangle budget. My biggest beaf is with the Game Override being ON and Hidden by default in the settings so I had no idea it was doing the ForceLOD0. I've said they should expose the Game Override in the default MRQ setting, because if I was aware of that I would have tried turning off the LOD0 setting.
@@WilliamFaucher I think I know the solution to your question at the end of the video,, I had the same problem scratching my head for ages. But if you go into the particular static mesh parameters there's a setting called screen size. Some times assets load in when the value is set to zero. You want to turn that value to 1 if that's the case then in the render que it will render out no problem.
Thanks! Been struggling with this - normal rendering works but MQR lost grass foliage in few cameras. The number 1 solution that is, just started cranking it up until I found the sweet spot.
so am already done adding my foliage ? should i delete that and crank that the static meshs screensize amount and then readd the foliage r would it update automatically ?
I always come back to your videos when I experience these types of issues and typically find the answer I need. I know I've used other tips from this video before, but today it was screen percentage that fixed some really annoying distant landscape flickering. Thanks for all you do, William! You're one of the few YTers that I follow religiously...
Hi William! Your videos have saved my projects many times, it's just a treasure trove of information in a condensed form, nothing superfluous, only the most important. Huge respect. But progress is breathing down our neck and already there are new problems. Now Nanite for Foliage raises questions. I think a lot of people will join my request, this kind of Troubleshooting is needed for UE 5.2/5.3.
The way that I manage to fix was going to the material property overrides of your foliage and look for the "Opacity Mask Clip Value" and changing to 0.05 or 0.1.@@alzate_3d
Don't know if you'll see this William, but I am a 19 y/o passionate only about art in life. My goal atm is to do this full time and your tutorials in unreal really do help with the chances of that dream becoming a reality. Thank you for everything you do my guy, you have a huge fan from India.
Man, every single one of your videos is just so thorough yet easy to follow and entertaining. Thank so much for taking your time to bring UE to beginners and creatives.
Another culprit for foliage disappearing (especially if it's just the leaves) can be the ""opacity Mask clip value" in your leaf material. By default this is 0.33, you can set it to something like 0.1 and your leaves will be visible from farther away.
To save a bit of perf on the second tip (Foliage mesh shadow wind issue), in the BP you make, make sure to add an instanced static mesh then add the fern to that.
Can you elaborate on this? When adding an InstancedStaticMesh under the root, and then assigning the static mesh in the static mesh slot, it does not show in the viewport. Do you need to add a StaticMesh component under the InstancedStaticMesh component?
Hi, William. My name is Alexander. I'm from Russia. I use a translator. Sorry for the possibly crooked translation.))) I had a problem in my last project on 4.27. I was shooting an urban area. The problem was the following: grass created by the foliage tool. It was visible only up close, on the middle and far background it was completely absent. But in the porthole she was, existed. That is, the grass was physically present on the stage and did not disappear anywhere, but it was not far drawn in the camera and in the render. And the problem wasn't Lodi The console command you mentioned at the very beginning of your video helped me. There was no such problem with the plants, which I just copied around the scene. And this problem was only with grass, there were no problems with shrubs and trees made in the Foliage tool.
I have just recently jumped into Unreal and I am still getting familiar with it. Thank you William! I appreciate all the help you're giving with these videos!
Thanks you for tips man. For the issue number 5, it happen with me when i paint so much the same asset, it's came the most of the time with tree and bushes. if it's gone when you render with render queue, delete a part of you paint meshes and retry render and boom, reappear. The solution i use for now when the problem arrive is to use a order asset of tree, bushes and you can continue to paint without any problem in Render queue. It's really anoying but easy to resolve.
I like the fact that you do troubleshooting videos!! alot of times the videos on unreal are like: how to do great stuff; but they never talk about the problems they had before finishing their amazing projects
Those first 30 seconds cracked me up, waaay to real for me! Thank you so much for your hard work putting these videos together and for sharing your knowledge, I learn a ridiculous amount from them every time!
goddddddd, i was looking for this everywhere and i always end up on your channel with my problems. You are a Legendary artist. Loads of love mannnnn!!!!!!!!!
Thanks my dude! It's such a weird issue I just... accepted in the past, I only found this workaround myself relatively recently. Hopefully this gets fixed natively in UE5 when it's 5.0 is released!
@@WilliamFaucher Yea that's a heck of a work around but sadly the issue is still there in the preview version of 5. I'll be shooting this video to a few folks I know because these issues really do need resolved they've been there forever
Thank you, William! Great tutorial as always! I've found another reason foliage disappears and how to fix it. Might help in case someone still has their grass dissapearing. When the material blend mode is set to "masked", the object fades out over a distance. So reducing the "Opacity Mask Clip Value" controls how far it fades out (it's located in the material details panel, under the "advanced" tab.) It might be obvious for someone working in game dev, but I've been pulling my hair out and losing all hope working with foliage in UE, lol.
another problem is with the shadow, which doesn't appear correctly when it's away from the camera. The command ( r.Raytracing.Geometry.InstancedStaticMeshes.Culling 0 ) in unreal engine 5 is apparently not solving the grass shadow problem
All your tutorials are gold information, however, I can say that this is one of the best lighting tutorials I have seen. Everything you say about maintaining a balance between physically correct light and things we can fake to give an artistic boost to our scene is as applicable to UE5 as it is to any workflow in any other realtime rendering or offline rendering software. . So to be clear, you are working your scene with Lumen and you only activated Path Tracing so you can have a visual reference of how the scene with Lumen should look.
The fact that you included the "Issue #5" makes me want to watch literally every video on your channel, because that level of "I want to help you guys" is unseen. Have a good one, subscribed, gonna go watch all your videos now and learn:D
I get awfully excited when I see you've got a new video out. 🤣 Seriously, my fav and most consistently applicable tuts. Thank you very much for all your hard work!
Just a note for UE 5.2+ The cmd r.Raytracing.Geometry.InstancedStaticMeshes.Culling 0 does not seems to be working anymore The way that I manage to fix was going to the material property overrides of your foliage and look for the "Opacity Mask Clip Value" and changing to 0.05 or 0.1.
I stopped using raytracing in my scenes caused fo this issue, now i can use it again. Better a bit uncomfortable workaround than nothing. Many thanks for the workaround
thank you so much this video fixed a huge issue for me and also boosted my FPS by like 30fps with the LOD part. Also somehow allowed me to up engine scalability from medium to high. Looking and running great now
This intro!... Those reactions are just at the heart of every UE environment artist. This whole video gave me some closure. Thank you very much. Also a suggestion on the disappearing foliage - might be wind animations just killing VRAM?
The first 1,000 people to use this link will get a 1 month free trial of Skillshare: skl.sh/williamfaucher11211 THE MOST LIKELY SOLUTION to the foliage issue I speak of in #5 seems like it could be the following: Thanks to @Adam Dotlačil "Like you mentioned, by default it forces LOD 0 on everything, but there is secret triangle budget for each instance. If it exceeds that value (likely to happen if you have a big forest), it stops rendering that instance, but still casts shadows (or at least DF Shadows) Two ways aorund it: 1.)

There is a console command foliage.MaxTrianglesToRender which you can increase (not sure about the default value). HOWEVER, increasing this value can drastically increasing rendering time, so I would recommend method 1."
For issue #5 If the scene is divided into several streaming levels (each person person working on a different part), and when all levels are loaded, the preview window will display it correctly, sequencer will display it correctly, render legacy will have it correctly, but render movie que will not show some things. Solution is to put those meshes inside the persistent map where the master sequence is, or right click on it in sequencer and convert to spawnable, this happens mostly with skeletal meshes.
i have tried everything. nothing was fixing the grass flickering for me... but then i added the screen percentage, didn't help. finally adding all the command listed up, worked.
Had this during development and searched for aaaaages deep in the web... and just turned of the wind. Thanks for this very helpful und structured video on these topics! :)
Foilage completely disappearing has to do with some frame buffer update, slightly modifying (painting) the layerinfo if its on landscape material layer seems to solve the issue, I didnt had any other similar bugs, yet. If its disappering on certain LOD distances I found out it has to do with texture mipmaps, especially on megascan assets that combine AO, roughness, Transparency etc in one texture the mipmaping of that particular texture needs to be set to either "LeaveExistingMips" or "NoMipmaps"; I assume transparency doesnt like mipmaps in LODs. I started using Unreal Engine for production (aka professionally) since 2 months now and your channel has been a HUGE help. Big thanks for all the videos you are putting out. 👍👍
Thanks William.. honestly you always answer the most important issues .. cant explain the coincidence of me just thinking to start asking myself about this issue specifically and ur video showed up !
Hey man, thanks for this video. You answered a few of my head scratchers in one go. Far and away the most I've ever learned about unreal has been during long nights spent troubleshooting strange problems. The rabbit holes go deep sometimes! I would love more videos like this where you troubleshoot rendering problems!
was just hoping you'd make a video soon and here it is! Thanks for the great content always. I've been starting with your earliest videos and working my way to current, lot of useful info! Love to MRQ stuff.
I had the same issue with disappearing foliage! I was placing foliage using my Landscape Material. In my editor, everything was visible, but the moment I pressed Play Mode, my foliage disappeared. I solved this by clicking on 'Build' -> 'Build All Levels' and deleting the HLOD in the process. I don't know what is causing it, and I figured it out through trial and error, but it worked. Since I have a solution to this problem, I actually don't care why it happens. I just click on 'Build All Levels,' and my problem is solved.
Wow! Thanks for this great tutorial! A had last issue with disappearing foliage when I've used standard Render Movie, to fix it I've used 200 warm up frames before starting render. With Movie Render Queue I didn't have such issue yet.
hello guys I have an issue with my grass in path tracing while rendering with MRQ , it flickers, a lot of jitterness like some noise patch, I've disabled denoiser and still nothing , it's only for foliage,anyone knows how to fix that , tried a lot of stuff ETA : okay so at 180 screen percentage HD not working but crank it up to 200 sceeen percentage to render and finally worked oufff after days and days of struggling you saved my foliage project - but beware guys it makes render very long You rock William 🎉
I do a lot of landscape with foliage renders in MRQ, so thanks for the tips about those issues - I was fighting with RayTracing shadows with wind before and just swithed it off until recently, and forcing the LOD 0 is a revelation for me (I will use it anyway even if its not on by default for renders from now one). For issue no5 - somebody mentioned that already - not using levels as "always loaded" for renders is a most common mistake I made and was infuriated by this before I finally figured it out. Very often when painting foliage I forget to place it in proper level, and I have lot of levels. Unreal 5 got rid of that problem entirely fortunately and in UE4 there is always "move to the level" tool and "place in the current level" option in foliage tools settings. When I cleaned up my scenery and remember to keep foliage in proper levels and set them as always loaded - the problem has gone for good. But issue #5 could be also related to using grass node in your landscape material. Grass cache really lags if you have a lot of dense grass and if there is really a force of LOD 0 this could get even worse, as it just have to load a ton of data into memory. So many times I had no grass in the beginning of the render and it was popping in in the middle of the shot. So it is generally better to use painted foliage for movie renders than the grass node or keep the grass really well optimised for lod0 and not too dense. Maybe using a console command "grass.FlushCache " in MRQ or the PIE version and high warmup could help - I didn't try that solution yet.
Thank you very much for the help with the foliage issue. And regarding the last issue part with foliage disappearing in the middle of the render I saw that same problem as well when I was doing an assignment and in viewport the foliage showed while it disappeared in the render. I had the problem with cinematic render part and I had to drag the top timeline so as to render the foliage. The cinematic render sequence timeline was causing the issue of foliage of my scene not rendering the foliage. Mine was fixed doing that so hopefully others might get it fixed this way
The only reason that worked is because it forces meshes to use higher LODs, which means lower triangle counts. Unreal has a hidden max triangle limit that culls away meshes/foliage when that number is exceeded. See the pinned comment!
Thank you so much! And a great intro. It's funny because it's true. That was the first problem I had doing a spaceship flying away from a forest shot! Mystery solved.
For issue #5, it appears that if your foliage actor is too big (in terms of bounding size), it COULD BE HIDDEN BY THE CULL DISTANCE VOLUME IF YOU HAVE ONE. This took me 3 days to figure this out. Just tweak your cull distance volume actor settings to fix this. Enjoy!
I've found another solution to fix the problem: - cull distance didn't do anything - I've just removed some of the trees and it worked. Remove trees boys. Thank you for the feedback lad, it's nice to see a wholesome community
Thank you WIlliam. Render videos in Unreal is always a pain. Lately I was trying to render a video of an enviroment I made. Lots of little but annoyng defects probably correlated to lumen in UE5. Hopefully your tips could help me to get something better!
This is such a great tutorial! William, all the problems I've been thinking about, You always solve it for me! Thank you, and thanks to you, I can make good videos. I'm waiting for your video.

Hello, How can we the Issue 1 with unreal engine 5 ?
The first 1,000 people to use this link will get a 1 month free trial of Skillshare: skl.sh/williamfaucher11211
THE MOST LIKELY SOLUTION to the foliage issue I speak of in #5 seems like it could be the following:
Thanks to @Adam Dotlačil
"Like you mentioned, by default it forces LOD 0 on everything, but there is secret triangle budget for each instance. If it exceeds that value (likely to happen if you have a big forest), it stops rendering that instance, but still casts shadows (or at least DF Shadows)
Two ways aorund it:
1.) In the MRQ setting disable Force LOD0 on Game Overrides. Then you can tweak LOD distance scale command to get the result you have in the editor.
2.) There is a console command foliage.MaxTrianglesToRender which you can increase (not sure about the default value). HOWEVER, increasing this value can drastically increasing rendering time, so I would recommend method 1."
I actually ran into that issue where foilage just disappeared from my render. I can show you the render if you'd like.
@@DannyNetwirk Are you using painted foliage or landscape grass type?
Great showcase of our pack in the beginning William, thank you! :)
Thank you for the free month of skillshare, the foliage lesson, and all of the other lessons!
For issue #5
If the scene is divided into several streaming levels (each person person working on a different part), and when all levels are loaded, the preview window will display it correctly, sequencer will display it correctly, render legacy will have it correctly, but render movie que will not show some things. Solution is to put those meshes inside the persistent map where the master sequence is, or right click on it in sequencer and convert to spawnable, this happens mostly with skeletal meshes.

10/10 William, wished i watched this before doing a render video scene in Ue4
The first 30 seconds are perfect. Basically everything I had encountered for the past 2 weeks 😅😅
This dude is Legend, extremely time saving stuff in this channel. Thank you.
Hi! Probably You know how we needed this tips, but I'm going to say it anyway! You don't know how it is helpful!!! Thank You!
Great intro! I like this change to the style of your video.
Thank you!
was just hoping you'd make a video soon and here it is! Thanks for the great content always. I've been starting with your earliest videos and working my way to current, lot of useful info! Love to MRQ stuff.
I had the same issue with disappearing foliage! I was placing foliage using my Landscape Material. In my editor, everything was visible, but the moment I pressed Play Mode, my foliage disappeared. I solved this by clicking on 'Build' -> 'Build All Levels' and deleting the HLOD in the process. I don't know what is causing it, and I figured it out through trial and error, but it worked. Since I have a solution to this problem, I actually don't care why it happens. I just click on 'Build All Levels,' and my problem is solved.
Thanks man, i was frustrated due to foliage popping issues
This is the video I been waiting for! Thank you!!!
Wow! Thanks for this great tutorial! A had last issue with disappearing foliage when I've used standard Render Movie, to fix it I've used 200 warm up frames before starting render. With Movie Render Queue I didn't have such issue yet.
hello guys I have an issue with my grass in path tracing while rendering with MRQ , it flickers, a lot of jitterness like some noise patch, I've disabled denoiser and still nothing , it's only for foliage,anyone knows how to fix that , tried a lot of stuff
ETA : okay so at 180 screen percentage HD not working but crank it up to 200 sceeen percentage to render and finally worked oufff after days and days of struggling you saved my foliage project - but beware guys it makes render very long
You rock William 🎉
Dude, thank you for sharing your knowledge in a clear funny way. You sir just got a new follower 👌
Working on a bigger project for my company and having issues with the grass just not being crisp enough and very noisy. I'll try this out!
Hope it helps!
@@WilliamFaucher Me too!
the intro had me dying because thats what pushed me to look up this video
So far the best instructor. 😍
I do a lot of landscape with foliage renders in MRQ, so thanks for the tips about those issues - I was fighting with RayTracing shadows with wind before and just swithed it off until recently, and forcing the LOD 0 is a revelation for me (I will use it anyway even if its not on by default for renders from now one). For issue no5 - somebody mentioned that already - not using levels as "always loaded" for renders is a most common mistake I made and was infuriated by this before I finally figured it out. Very often when painting foliage I forget to place it in proper level, and I have lot of levels. Unreal 5 got rid of that problem entirely fortunately and in UE4 there is always "move to the level" tool and "place in the current level" option in foliage tools settings. When I cleaned up my scenery and remember to keep foliage in proper levels and set them as always loaded - the problem has gone for good.
But issue #5 could be also related to using grass node in your landscape material. Grass cache really lags if you have a lot of dense grass and if there is really a force of LOD 0 this could get even worse, as it just have to load a ton of data into memory. So many times I had no grass in the beginning of the render and it was popping in in the middle of the shot. So it is generally better to use painted foliage for movie renders than the grass node or keep the grass really well optimised for lod0 and not too dense.
Maybe using a console command "grass.FlushCache " in MRQ or the PIE version and high warmup could help - I didn't try that solution yet.
I tested it just to be sure and MRQ really does force LOD 0. Yay! :)
William solving mysteries again ! Thanks
Love your videos dude, how often do you do streams?
That intro was gold :D
Thank you very much for the help with the foliage issue. And regarding the last issue part with foliage disappearing in the middle of the render I saw that same problem as well when I was doing an assignment and in viewport the foliage showed while it disappeared in the render. I had the problem with cinematic render part and I had to drag the top timeline so as to render the foliage. The cinematic render sequence timeline was causing the issue of foliage of my scene not rendering the foliage. Mine was fixed doing that so hopefully others might get it fixed this way
The only reason that worked is because it forces meshes to use higher LODs, which means lower triangle counts. Unreal has a hidden max triangle limit that culls away meshes/foliage when that number is exceeded. See the pinned comment!
Best Tutorial ever .
Super Important topics .
Thank you very much! Your Tutorials helped me a lot to get closer to photorealistic results.
By the way, I loved the intro of this one! :)
Thank you so much! And a great intro. It's funny because it's true. That was the first problem I had doing a spaceship flying away from a forest shot! Mystery solved.
Great workaround, William. Thanks for this.
Cheers! Thanks for watching !
Finally I asked for this! A couple of months ago thank you!!!
Unreal Sensei, thank you William !
Hahah that's funny because there is literally a channel called Unreal Sensei and that's not me! :P
... best intro ever 😎 great video!
I have asked chat GPT in regards the first issue and it didnt help me but William did! Thank you !
For issue #5, it appears that if your foliage actor is too big (in terms of bounding size), it COULD BE HIDDEN BY THE CULL DISTANCE VOLUME IF YOU HAVE ONE. This took me 3 days to figure this out. Just tweak your cull distance volume actor settings to fix this. Enjoy!
I've found another solution to fix the problem:
- cull distance didn't do anything
- I've just removed some of the trees and it worked. Remove trees boys.
Thank you for the feedback lad, it's nice to see a wholesome community
Thank you WIlliam. Render videos in Unreal is always a pain. Lately I was trying to render a video of an enviroment I made. Lots of little but annoyng defects probably correlated to lumen in UE5. Hopefully your tips could help me to get something better!
The best intro! Thanks :)
Nice Intro Mate! and nice video!
This is such a great tutorial!
William, all the problems I've been thinking about,
You always solve it for me!
Thank you, and thanks to you, I can make good videos.
I'm waiting for your video.
actually a watchable intro. I've been proven wrong about intro videos
Hahah thank you so much!
William you are my saviour! thank you sooo much
