I opened up Muse Texture Generator and typed “grassy floor” and got a nice grassy texture. When I try to drag that onto a game object it doesn’t work but rather gives it a blank MuseMaterialShaderGraph material without any textures attached. If I instead first drag it into the Project window and then onto the object it works, but when I try to tile it I get this:
I tried to use it intuitively, rather than reading the manual, so maybe I just did it wrong. However, if this is the case then I strongly suggest you allow dragging the material straight onto objects. Am I supposed to go through some sort of export process first? Again, this seems clunky.
