Idk ,why grass dont show texutr on this ground?
Evry object in this coletion have texture .
Where is problem then?
Can you show us the material settings for the grass?
That setup should work fine,… the only way I could break it was by disabling nodes here (but there may be other settings I am not aware of that break shading) :
Idk, I had that same settings, moment ago I fixed it - somehow.
