Ok I must really not be getting this haha
I got it to show up, but I can't get it to make a dent in the ground (always raised this much) and it's not rotating at all.
I connected the transform input shader to the input of the image map shader, if I connect it to the image's mask it doesn't show up at all. I've attached the tread I'm using.
Thanks for the help so far!
UPDATE: I managed to make it create a hole of death, I created another surface layer and connected it that way so now it's going underground just fine. It's still not rotating properly, though.
UPDATE 2: It's being affected by my other shaders, warped and messed up a lot - this'll be a problem anyway, how do I make it so my other terrain shaders (cracked floor, rock generation) don't touch this?
UPDATE 3: I've rotated it and found out how to get it masked properly. It's still being affected by the other shaders so the effect is being lost..
UPDATE 4: This might not be too bad, but I'll need to figure out exactly how to 'end' the tracks at the front tires, that's lost on me right now. It's kind of a subtle effect right now:
UPDATE 5: Figured out how to end the tracks. Shader arrays! Still would be nice to know how to give some shaders priority and not be affected by others.
