Skatter Grass even tips

Dear SketchUp Community,
this is my first post in forums in general so pls be kind xd.
It is motivated because of a problem that I face when skattering grass on a straight face.
Sketchup somehow evens out the grass tips automatically, which obviously ruins the whole thing because everything below the grass tips gets blocked by the face they were shattered on. I heard it´s because the texture has “grass” in it, but then I don’t know how to rename the texture and import it in sketchup without the skatter library.
Thanks for your help in advance,
CW
