How To Spawn GRASS And SMALL FOLIAGE | Unreal Engine 5 tutorial

Hello there! In this Unreal Engine 5 tutorial, We will learn how to spawn our grass or foliage from within our material using Grass node/ Grassmap from within our material.
We'll start with using simple landscape layers for the grass, then learn to use custom alpha/masks, learn how to use Splatmaps for different grass layers and debug visualize the grass in UE5.

Great tutorial, you've got my likes and sub that's for certain. Thanks for the "debug" section it helped me a lot.

[@CrowBiomes]

The grassmap node needs to know where to spawn the grass. When we put landscape layer sample in material We are saying spawn grass wherever this layer is. So if the layer is not there, it won't spawn. If you want to spawn it regardless, put 1(or a mask where you want the grass) and it will spawn it everywhere.
(If the grass won't show, make sure you are not in low resolution where foliage is 'very low' and you can clear grass cache with "grass.flushcache")
Did that answer your question?

Exelent video 💯💯🔥🔥!!, thanks, can you do a tutorial about the manikin all over the landscape please, it looks very usefull to compare the scale of the landscape

[@CrowBiomes]

It was discussed in the Procedural foliage spawner video. It's like spawning trees with less steps.

[@robertroder5601]

Is there a way to exclude the PFS foliage position from the Grass Types? So let's say I want to spawn big bushes in the PFS and don't want the Grass Types to intersect with them.

[@CrowBiomes]

There can be a few ways but It's not a big deal even if they do intersect(even when there is a way, it's not worth the extra effort+ performance loss due to extra steps). Assuming you want something like no smaller foliage can grow in the area close to where certain type of bush grow, in that case you'd make a separate landscape layer for that and exclude it from PFS.

worked with sand layer but with rocks wont work (( maybe because of Lerp, idk

Hey Klaus can you make a tutorial on how to create Rivers and lakes in ue5 after importing a landscape. Great vid as always!

[@CrowBiomes]

It's in the plans. Will use both water system and surface output from Gaea. Hmm, if my memory serves right, you suggested this earlier?

[@neeedsmorebeer6573]

@@CrowBiomes I would like to see this as well. Great vid!

[@nikuto1315]

If I have an auto material for my landscape ins it possible to prevent grass from spawning on cliffs and things like that.

[@CrowBiomes]

Yes, Subtract whatever is responsible for that texture from the corresponding grassmap. If cliff is a layer, then subtract a layer sample with the layer's name. If it's auto blending, subtract whatever you put in alpha to blend the cliffs.

@@CrowBiomes thank you very much.

[@christianmartinez351]

Thanks friend.. help me please.. the alpha images are color red and balck.. how to change the colors white and black??? thanks

[@CrowBiomes]

You don't need to, The data is there in a single channel rather than in all 3 - RGB vs R

[@caution5862]

hey Klaus can you share your material or maybe some screenshots or just some details about it your Landscape just looks so realistic I tried to follow up in other tutorials as well but it doesn't look that realistic

[@CrowBiomes]

Hey man, the final material is patreon exclusive but I've talked about some of it in this video here - th-cam.com/video/j1AekcZeOKc/w-d-xo.html

[@loremipsum3147]

Does this node or workflow exist in UE4?

[@CrowBiomes]

It does, Same for Unreal Engine 4.

[@HorpOnAir]

Does unreal engine 5 editor support multi gpu plus ?

[@CrowBiomes]

Not sure about that, I think they added it for baked lighting back in 4.27 but that's that

Some of my grass is floating ...
