trying to recreate your material for the grass. i am using the speedtree hero grass for the purpose of testing.so i figured your network except the world position part.
in ue 4.14 i cant locate the “WorldCoords -XY” expression but there is “WorldPosition- XY” how did you use that? and what is the texture that u r usind right after? i guess it is for wind like some kind of rgb wind?
also it will be great if you can tell a bit on your lighting process
thx and great work.
