I know how to add these as objects but isn't there a way to get 3D grass on displacements without having to throw on models?
you can make some prop_details and go under the category foliage. There's lots of trees, bushes, shrubs, etc. in there.
Yes Open, it is a line in the vmt part of a texture. Here is an example: Code: "WorldVertexTransition" { "" "Nature/dirtground002" "" "Nature/dirtground001" "%tooltexture" "Nature/blendgroundtogravel001_tooltexture" "" "Nature/dirtground002_normal" "" "Nature/dirtground001_normal" "" "Nature/dirtground002_blendmask" "%keywords" "tf" "%detailtype" "tf_grass" "" "dirt" } Its the '"$surfaceprop" "dirt"' line.
You are using a blend material on displacment correct? You can filter the tex by 'blend' and you'll see the existing choices. Then 'paint alpha' with the displacement tool, the more you paint the more grass you get.
