Can i weight paint a logo? Hi i woul like to paint my logo on a weighmap for my grass system but i cant figure out how to change the brush or use a texture like in texture paint mode. Is it nor possible? Should i draw the logo on hand?
Not a direct answer to your question, but you can also use both procedural and image textures to drive the length of your grass:

Hair_Length_by_Image_Texture.blend
