Okay, so how the regular sidegrass works, the sidegrass texture can use transparent parts and have the dirt texture automatically placed beneath it. Like this:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I uploaded my Shroomy Side Grass in the same fashion, expecting it to also place the dirt texture underneath it, but when done, the sidegrass 'floats', leaving the transparent areas in-game, well, transparent.

I'm wondering if it would be possible to have the dirt texture also placed underneath the Shroomy Sidegrass. Thanks!
