Hey all, just an extra note: If you get errors about BurstCompile, the generate functions use Burst Jobs, so you need to go to the Package Manager and install Burst if it's not installed already!
I'd love a guide on the cutting and burning :D I've been trying to do what you did but don't really understand any of it xD I'm in love with this tool though
Your work continues to be an inspiration, super clever stuff. It is extremely generous and appreciated that you share all this knowledge for free. You're a legend
You are a goodsend!, I was just reciently trying your older tutorials but couldn't get the tool to work and you just saved me dropping this video, a million thanks and your work is amazing
You shader is absolutely insane! It's a real pleasure to use! And please do the guide to cut and especially burn the grass! This is great work! I love your shaders!
Bro, all I can say is great job! I've been using your grass from day 1 of my career as unity developer. I've been loving your work ever since and this update makes it more amazing! I also want to thankyou for making this project to the public! Great job!
I don't know why dont you have millions of subs and viewa. Excellent job ! And I don't mean this video. Your website and the other tutorials. Keep it up !
After trying a lot of packages without any success, I finally tried yours and I have to say that you have done a fatastic job. It looks like magic, only one batch to render the grass and it works perfectly on mobile. This is exactly what I was looking for! It would be better if you could create a package to make the setup process simplier. And for the blend texture terrain, may be there is a way to directly get the terrain texture instead of using an extra camera but I don't no if it is feasible, just an idea. It is a very incredible how performante it is, thank you so much for sharing it! Last question about the licence of this tool, do you allow people to sell a game using this tool? I have seen nothing about it on your Patreon page so I prefer to ask.
I wasnt getting shadows on top of the grass from other objects. I assumed it might be related to the material generated for the grass so I messed around and the only way I could get it to work is by setting the shader to produce "lit" rather than "unlit" but as it looks the same either way im happy with the fix.
Amazing & well documented! Overview points you went over are super nice touch as well! As the buffer sends the into to shader graph, Is it possible for artists to tweak appearance, etc, etc on grass blades?
Something is wrong with the shadergraph! I followed the instructions and put in the hlsl file. But the nodes that go into those nodes don't exist because my Unity says they are custom. Things like "Vertex ID" and "ColorPaint" have an error next to them that says "Validation: This node type could not be found. No function will be generated in the shader."
@MinionsArt thank you! Sort of a side question - could you do a video or link to some documentation that talks about your workflow for those nice base textures used? The hand-painted looking green terrain under the grass looks great, would love to know more about how to create something similar :)
If you are having issues with the paint tool not drawing the grass, import the .shader file from her post, create a material out of that, and set the brush material to that created material. Your project may not be using urp and that seems to be the issue.
@@liamassassingaming922 isnt really possible since all placing scripts are written with the unity editor libary. u would have to rewrite this part completely new. u could try a former version of this grass shader. this is a bit easier, but still a pain (i gave up on this aswell bc it got laggy very quick).
Thank you for the shader and the tutorial. I am having an issue where the grass won't paint. When I check "Paint Mode" I can see the green circle in the viewport, but when I left click, it selects / drags out the viewport selector box and doesn't paint grass.
Great work, and thanks a lot for the tool. A question, at 8:58 you haven't yet set the color of the grass. I get the same grey grass even after changing the Brush color on the Grass Tool And the Tinting Settings on the General Settings. Any idea what might be causing this ? (I fixed the Shader Graph like you showed and I get no errors.) Thanks :)
If anyone else has an issue where the material you created from the shader is pink, try going into your project settings -> Graphics and making sure the scriptable render pipeline settings is set. Took me a while to figure that out sadly.
@@KaganParlatan Hi! So this asset in particular, no this can not be done. The best place to start for procedural runtime grass is feeding mesh data into an array and using that in one of unity's GPU instancing methods.
You can use Instancing with triangle-strip. Instead per-vertex data use per-instance data. In shader code you get vertex index, so you can build grass blade directly in vertex shader. Compute stage is still needed for culling or wind lookup. But less memory bandwidth be used. x5 less data will be transferred through memory. The perf gain is even greater if you use more vertices per blade of grass. Why does this affect performance? Memory is dramatically slow. You can win x2 performance on this without any other tricks.
Hi! i'm making an indie game with a friend and tried using your grass which looks great! Is there a way to use this grass in our game when publishing it? Hope it's okey to ask!
nice i like the grass feel like in the morning when i wake up and smeelll the cows and grass and the different flower like a small flower or the big and different grasses hehe nice
I got this to work in HDRP by opening the ShaderGraph, manually setting grass.hlsl in GetGrassData and the Blending Texture, and changing the Active Target to HDRP. Then it should be straightforward to follow the setup like normal.
It's now basically just a shader graph plugin (or just a surface shader) so it reacts to diractional lights however the basic shaders work. You can adjust it easily, all the compute shader parts are inside of that GetComputeData custom node, you can change the fragment block to work how you want :)
Awesome stuff as always. I have a question: How can I make the grass affected by ambient light or change colors at runtime? When the day turns to night, the grass looks brighter than everything else, which doesn't look good.
Awesome job!! Love your work, running into an issue with the BiRP, I can get this to work with URP but Not sure what I’m missing using the built-in, no errors after setup but nothing shows when trying to paint the grass Same steps as URP but Created the material using the proper shader you mention for the BiRP but just seems to not generate any grass… aside from the shader to generate material is there some other step needed for using built-in?
Hmm the original version is made for BIRP and ported later to URP, but it is in later unity versions, are you using an older version maybe? Missing a camera with MainCamera tag?
@@MinionsArt Just tested with the latest builds for 2021 , 2022, and 2023 with the same results. The process seems to go smooth using URP and it Paints the grass with no issues but no luck with the Built in. it acts as if its painting but it does not seem to render any grass within the Editor view or Game view. I did verify the MainCamera tag is showing for the Main Camera when generating a new scene. other than compiling the Material from the GrassSurface.shader is there a different step needed for the Built in? Doesn't seem like there is any configuration needed for the shader other than making the material like with URP, unless im missing something there again much appreciate the work you do and the help you provide!
The patreon file is correct, it's the same as my working version in 2021,2022,2023, I'm not sure what else could be the issue. Are you targetting a non-windows platform or something? I had an issue before where the grass would render to a random other tab that was open somehow, could that be it?@@drzbabiboi
@@MinionsArt just as an update I tested the old build using the built in pipeline and it seems to paint the grass with no issues. I’m sure I’m just missing something simple in the setup process for the new setup because the tool does show that it’s generating grass but it’s just not showing the grass within the scene
I want to use manual update after game started how can i do that? Since my game is multiplayer and players spawn at different times after the scene has begun , I need to update after every player has spawned. Other than auto update because u said it is very slow.
I've juste managed to do it, sorry, 1 year late but you just need to do this : When your player spawn (or any new GameObject in the scene) you need to call the function Reset of the class GrassComputeScript. You can do that in your network manager that calls the Reset at each spawning. To do this, set a reference to the grass object and the GrassComputeScript like so : GameObject grassObject; GrassComputeScript grassCompute; Find references to the grass object and script with this code: grassObject = FindObjectOfType()?.gameObject; grassCompute = grassObject.GetComponent(); And when spawning, call : grassCompute.Reset(); More infos in the GrassPainterWindow given in the files in description. Have a nice one ! 😁
I am in URP and I follow the steps here correctly, having a mianCamera with correct tag but can't able to see any grass being rendered in scene/game at all. Although I can see the grass count going up after painting. Much appreciate any help if possible.
