i want to modifie the coagulation one to be a bit more grassy but idk how to do it :/ when i import it into gimp its missing stuff... help please

Isnt GIMP for pic editing? lmao

Yes it is and he wants to edit the ground map "picture."

Oh.. lol I thought u meant model wise, just get a different bitmap, why would u edit it?

i think that the ground enviroment maps are part of layers so you may need to change layers to get the correct one.

You should first try editing in the shader. You can make it all grass, or grassier, in the shader_environment for the ground (use guerilla).
In GIMP, right-click the layer and Remove Alpha Channel.
Then Right-click and create layer mask.
Choose all white.
Now make sure you're editing the mask by clicking the thumbnail to the right of the layer thumbnail.
Choose a black brush and paint over the parts you want to be grass. They will turn transparent.
Save, and overwrite the bitmap. Back up the ground.bitmap first.
