First of all, great tutorial series. Second of all: Thank you SO MUCH for marking up your UA-cam timeline. It makes it so much easier to look back at the tutorial and find specific bits of information I need to refresh myself on
Glad it was helpful!😊
this program works great! exactly as I wanted
Thank you very much, my friend you're the only one who shows us how to create a grass scene from the beginning + your way of teaching is great. Keep up this great work 👌🏻
You are welcome 😊. Will do !
Great tutorial. I find it especially helpful that you also talk about your misstakes, how you learned this yourself and aditional ways of solving things.
Glad you enjoyed it! Thanks for letting me know.
The fact that you can type "pi*2" into a field and it will give you the proper numerical value of 6.28. This, to me, is one of the millions of little ways in which Blender truly stands out. Try entering pi into a rotation field in 3ds Max.
There's an even shorter way. Write "tau". It will automatically calculate pi * 2 and the result will be 6.28. Blender is amazing, Ma shaa Allah.
Totally love the feature and Blender of course!
It is AMAZING, mashallah :D!
i really apreciate your help with dowloanding this software
Great tutorial and great editing/youtube timeline-marking job!!
I found this very useful! :)
Thanks a lot, glad it was helpful!😊

You're very welcome! 😀
man I missed this kind of tutorials lol. Great work here, thanks!!!
So glad to hear 😀
Scatter some rocks lol
nice tut brother! thanks
😂 You're welcome
Hello 👋 love your videos! Is it possible to use more than one vertex group on the same plane? Like to make for example a stoney path on a grass, with out such an effect, where the grass sticking out of the stones? To have a grass small in the area of the stones. Maybe it could became a tutorial? 😁😍 stay healthy and thank you👍
Glad you like them 😊. Yes, you can use multiple vertex group on the same plane.
thank you dude!
No problem!
thank you bro thank you
My pleasure 😃
thank you so much bro
You're so welcome 😁!
tnx bro you r a life sever
No problem :)
wow dude i did not expect such a well explained tutorial that is applicable on so many different things! Is it possible to use geo-nodes as well for creating a creek of water in a grassy environment like this?
Yes you can! (I think so)
thanks for sharing
You're welcome 😊
merci bg
i have question, with partikel sistem we had childern where partikel render can be multiplier without show the partikel in viewport render, is this method still usable for large scale distribution of grass/tree? or just use for low scale?
Thanks!
No problem!
Thanks sensei ! You make really nice content... Have my follow :)
Awesome, thank you!
wow
😊
Instead of using different layers, you can use "fields" part of the whole thing by sending different density depending on the instance index.
How ? can you send a screenshot or something ?
@@CGObaid Instance on points has instance input. And it's a field. You can set the index manually, or plug in a random value node. If you then do some math with output of that node you can calculate necessary density procedurally or just use switch node based on value you get. All necessary nodes work with the "fields".
thank you!!! video liked and u got a well deserved sub from me!!!!
Awesome, thank you!
On the subdivide thing, instead of adding the modifier, you could go into edit mode and just subdivide with a right-click.
Yeah you could, but then if you wanted to change the amount of subdivisions later, you won't be able to do so.
Doing it in geometry nodes will enable you to change the amount of subdivisions at any time you want.
@@CGObaid Oh, right. Procedural. 😁
Seprate rocks😂😂😂😂
The rock:-u just chosed death🤨🤨
Nice
Thank you 😊
Dear sir, the node group for displacement is brilliant. It is always a bother when you do this in a regular way. This group handles it by changing one value. I going to save this as a separate modifier to use time and time again. Thanks!
You are most welcome 😀!
Accidently set density to 30K, see you guys in 4 months!
But for real: good tutorial, I just had a bit of a hard time understanding you sometimes since English is not my native language. I also used the to radians converter in the math node instead of entering tau, I think it will be easier for future me to understand what I'm doing there :D
Lol 😂. Thanks a lot 😀! English is neither my native language. You did good job there using the math node.
With particle systems, you can add children particles to control the amount of instances visible in the view port and control the percentage which are to be rendered. This helps with keeping the viewport form lagging. Can that type of set up be created with geometry nodes?
I haven't found a solution for children particles system in geo nodes yet, but you can easily set a different Density for the Viewport and the Render in geo nodes. I have made a video on this - ua-cam.com/video/pM0ekmt-x40/v-deo.html
Btw to increase the probability of an object in a collection you can just duplicate it in the collection(think of it as .../10or out of any number) I have seen people do this but.. I haven't so yeah
Haha good tip. But you should link duplicate it, would it still work then? There should be a way to do it without duplicating 🤔
Is there a way to use a weight painting to control the grass or rock location? Similar to the old particle system?
Yes there is, I've explained it in the video. There are also timestamps available, so you can find it easily.
What a great tutorial man !!! But i got a problem on Distributing Instance, why you got so many object with 10 density in there ? Cuz in mine, i got less than yours. Thankyuuu !!!
Thanks 😊💕 It depends.. Maybe because of the scale on which you are scattering or maybe you are using a different value for the density max (if you're using Poisson disk distribution)
Really good tutorial. One thing, that would be really cool to add, is a node setup so that grass can't spawn inside rocks (intersecting) or near them. Is there a good way to do this procedurally?
Yes, it is possible to do with geo nodes but I've to figure out how to do that. But you can achieve this effect with just a few clicks using Scatter 5. I showed how to this in this video - ua-cam.com/video/p06R8pC_sno/v-deo.html
yes please show how to add grass hair particle system applied to a geo node landscape/path. I would like to know how to prevent the particle system from going into the path
is it possible to make a game texture from this grass?
Way too much for me to follow here, but this was a great tutorial for giving a sense of how to use these nodes. Thanks!
Glad it was helpful!
the final result is amazing. I'm confused tho. So you used plants from gscatter but you didn't use the gscatter nodes, you rolled your own? Am I understanding that correctly? thx
I'm very glad you loved it!
The tutorial is about Geometry nodes. But instead of modeling the grass by ourselves, I just used models from Gscatter. Feel free to use any grass models you want :D!
@@CGObaid ok, thx. I will need to spend some time seeing how this gscatter works or maybe it's better to create your own geometry node setup. So many diff ways to do it.
@@CGObaid Okay, I installed Gscatter 10, 11, 4.... none of them have the grass object you used and I wondered.... is that a free grass that came with it or can you somehow send that grass asset to me in some way? The only free assets with these gscatter versions is plants that have leaves. I like this grass you used! How can I get that? I guess I could look if it is for sale on their site. But I'm only doing Blender for fun, not income. If you know where I can get the grass models you used with the textures etc, let me know. thanks! I made a geometry node setup like yours so now I have a ground displacement going. I will try to finish it like yours then save that as some template for future landscape stuff. thx!!!
Sorry for the late reply, but Gscatter has changed quite a lot since I made this video. But the assets I used are still free, you just need to create a free account at Graswald then you can download it from the Gscatter downloads section on their site
@@CGObaid I couldn't find those particular grasses for free. I think they quit offering those. I emailed also about it so I just gave up on that and really I haven't messed with Blender in months. I guess I realized it was just too difficult to get any cool results. It was super frustrating trying to remember all the GOTCHAS and try to avoid them like..... apply all transforms cuz yeah, that weird effect that's happening that you can't figure out? You didn't apply scale and now EVERYTHING is hosed. So.... It was cool to play with for a few months. I dabbled with the sculpt stuff too but it's too involved. Thanks for the reply, tho!!!
Do we have to apply the geometry node modifiers before rendering?
No you don't have to
In the Shading mode Sky Texture, mine said "Nishita not available in Eevee" how can you fix this?
In render settings tab switch engine from Eevee to Cycles
This may not be possible, but I just wondered if it is possible to alter the hue, colours, of the grasses after the last join geometry node? Or somewhere. My aim would be to be able to vary the whole 'colour cast' of the node result, to vary the grass between a lush green and a summer parched dry yellow. Though perhaps each group having that ability may be better, as each species of grass may suffer from drought conditions differently.
Do you mean color variation to the grass ? You can easily do that changing the grass hue using the object info random value. Here you can watch a video by CG Geek -ua-cam.com/video/-GAm-7_3N6g/v-deo.html
The main point starts at 6:53
@@CGObaid That works in the material nodes. I was hoping there was a way to 'tint' the entire geometry nodes set up towards a lush fresh green spring look, to a parched yellowing dry summer look. Rather than have to go to each material and alter them one at a time. It may just not be an optiong.
Хоть я ничерта не поняла, потому что всё на английском, но по уроку всё получилось сделать. Спасибо!
Рад слышать! Я не знаю русского, поэтому мне пришлось воспользоваться переводчиком, чтобы понять ваш комментарий :D
Try zooming in (ctrl+scroll)
Thanks for the tip !
Amazing thank you! question what is the "Edge" key?
No problem ! what are you asking ? can you give tell the timing ?
@@CGObaid Thanks for answer, i find out is The "H" key hehe not "Edge" hehe thank you for all your tutorials
:)
Is it good to buy a laptop which have both
mx 450 graphics (2GB)
And intel Iris XE graphics (4gb)
With i5 11 generation processor and 8 GB Ram
For blender beginner
I don't know about the Intel Iris XE . I am hearing about this graphics card for the first time But Nvidia Graphics card are the best. Either GTX or RTX are better. My pc has GTX 1660. Intel i5 and 8 gb of ram are pretty good.
"There are better laptops with great CPU, GPU and RAM combination in the same price range as in Iris Xe." - (from Quora).
Can i use grassblade, scatter 5 add ons
instead g - scatter??
You can use whatever you want :)
How do you add color variation to the grass instance?
Create multiple stops in a Colorramp with different green colors. For the factor use the "Random" output from the "Object Info" node. Then add a Mix color node after the Base Color texture of your grass, set the blending mode to "Hue" and use the Colorramp for the bottom socket. The fac in the Mix color node will control the intensity.
Very good tutorial, bro, can add-ons be implemented using the particle system in Blender 2.93?
How to make grass react to the wind modifier? I mean the wind can sway the grass.
I don't really know. I've seen some people doing it using math and textures stuff. When I figure a way out I'll make a video on that as well 😃
For some reason its impossible to install the add on, I have tried to other addons aswell, both zip files and they work well. So I don't understand what the problem is?? Super grateful for all the help you can provide ty.
nvm fixed it
Awesome ! how did you fix it ?
@@CGObaid I e mailed the developer of the add on and they told me that I probably installed the wrong file and sent me another link which worked ¯\_(ツ)_/¯
Hey I have a question. When I change the scale of something or change the rotation or whatever, I can only change it in 0.100 steps, but I would like to go with 0.010 steps. How do I do that?
Hold shift while you drag it or type it in manually (there's a little box in the corner after you let go of a transformation that you can expand and type in specific values) :D
@@ihatechalk2982 Thanks, thats what I wanted to know. :)
is there a way to make Geo node grass affected by wind/turbulence?
You can fake grass wind effect using noise texture but there isn't a way to use force fields inside geometry nodes yet.
I think rocks look much better if they a bit in the earth, and not lying on it as if it was rock solid.
what is your z Displacement Node ? how i can get this ? waht tutorial you show this please ?
I made it in the first part of the series - ua-cam.com/video/yZgLhffsVd8/v-deo.html
How do you get your grass to not clip through your rocks?
It's actually not a big deal if the grass clips into the rocks unless you're close to it. You can do it by Realising the rock instances then using a Geometry Proximity that acts as a mask for the grass layer, but that will become very heavy. Instead you could add a Instances to points node then use that for the Geometry Proximity, be sure to set the mode from faces to points. This will work a lot faster but the masking won't be as accurate.
Make a tutorial on wind swaying the grass please.
Well, that's on my list :D
BEEST!!!
You are the best 😃
Hi guys, I have a beginner question. Is there a big difference between using particles and geometry nodes? I am talking about performance and rendering
Great question which I don't know the answer to 🤣 Thanks for asking, I'll let you know when I find the answer :)
I wonder why my grass is still floating after I reset the children. I tried applying the transformations. I don't know how to get the grass to be on the ground.
The origin point of the grass needs to be at the very bottom. You can go to edit mode, select the bottom vertices, then press "Shift + S" choose "cursor to selected". Then go back to object mode, right click and change the origin point to 3D cursor.
Gscatter doesn't have a zip to install. I've unzipped the folder it gave me and tried it. Couldn't find the .zip in it so I used the unextracted version and there's no .zip in there to install either. I've tried for an hour now and can't figure out how to get Gscatter into Blender.
Both materials I also tried to install and the download button didn't work even after clicking multiple times. I clicked through a few options and nothing works. Clicking a file type just opens up another window to view it. I set it to 4k and Blender and have tried setting it to .ZIP instead of blender and the Download button does nothing. I tried going to a completely different texture on PolyHaven and they don't download either so I can't move on past the first few minutes of this tutorial :(
If you download the free version like me you must go to the blender file inside the folder copy the grass you want and paste it into the tutorial file and go on. but if you want the addon it’s not free (;
Awesome tutorial.
But i got a problem
How to make a grass on large scale like on 1000 meters?
It's very simple, just scale the plane to 1000 meters and scatter the grass. But you're pc will lag a lot and blender will crash
@@CGObaid thanks
@@dlebar9962 But on a very large scale you don't need the same amount of grass everywhere, because you won't be able to see the grass which is far away.
@@CGObaid i know
i didn't get the free assets like the free assets.JSON is there but it didn't give anything
A lot has been changed to the Gscatter addon, you can find their updated tutorials here - ua-cam.com/play/PLOA3PJ1m8P7sIyw7bY2bYRqaS-sUTd7AZ.html&si=L7KueJ4vpdmOWMvC
If you're having any problems with their addon, then kindly contact the Graswald team
Don't worry about the seed so much, crank it into hundreds carelessly. It doesn't matter and easier to avoid overlap.
Thanks for the suggestion
Grass you used in tutorial is no longer available ??
I think you just need to download the assets separately from the website then install them in the gscatter addon. A lot has been changed to the Gscatter addon, you can find their updated tutorials here - ua-cam.com/play/PLOA3PJ1m8P7sIyw7bY2bYRqaS-sUTd7AZ.html&si=L7KueJ4vpdmOWMvC

@@CGObaid thanks 👍 I'm excited to be able to follow this tutorial. Great job
@@Alexandrezification No problem😊
16:05 - 16:30 lolol
whoops.. I forgot to edit that part 😅🤣
what about performance?
Can you expand your question please ?
Why don't you just click on bentgrass or whatever and click on "scatter selected?" Graswald is designed to automatically do all the geometry nodes for you.
You can then adjust distribution, scale, rotation, randomness, and all sorts of things through the Graswald menu. It's all right there.
It's because the tutorial was not about G scatter addon, It was about geo nodes. I have created a video on G scatter in the past. In this video video the purpose of using g scatter was only for the grass models, but you can use any grass models that you want. Hope it clarifies your question :)
OKay i have 1 issue When i scatter Grass it Viewport is lagging as all hell i cant even open it in solid i need to open it in wireframe to move properly
My spec is
Ryzen 7
GTX 1060
Ram 8GB
Does it lag even when the amount of grass is low ?
Mine lags as well when I set it to a high amount. So I keep it at a low amount for the viewport & for the render , I increase it.
@@CGObaid imma try it
@@CGObaid Found it Cavity is Screw with me
