If I want to populate the world with some grass, which tool should I use.
Shall I paint the grass like it is normally done with trees (foliage tool) or is it better to use the Landscape Layer Paint Method for setting grass meshes like it is done in the following tutorial:Quick Unreal Engine 4 Grass Tutorial - YouTube using both methods, but so far I can’t see any significant difference in the performance.
I have been using foliage for more control.
the grass tools just scatter too much grass everywhere and you can’t really blend the areas in between the different types to my taste.
performance wise it’s the same mesh with the same LODs and the same settings so you shouldn’t see any difference at all.
- grassmaps (landscape layer method) won’t have collisions… in case you’d be adding rocks or something that needs collision.
It really depends on your circumstances. I’ve found that with grass/bushes/rocks etc, it’s better to use the landscape layer grass method. That way, when I paint a new layer, I don’t have to go and change the foliage manually. I usually use the Foliage tool for larger meshes (trees, larger rocks, etc).
