I use joints (rotation only) to animate a scroll opening up into a letter (done in Maya).
The texture is a single cream colour, with text on top of it. I export the scroll (with the texture applied to it) into Unity and my texture is looking quite odd. Not sure if its Unity, or Maya rotation, and showing those dark patches?
Check your normal, you might need to update them while unrolling.
I somehow fixed it, then needed to re-do it but forgot how I fixed it. Chose ‘soft edge unlit’ shader and it worked. I should have just played around with more that 3-4 of Unity shaders. I was going to ask an admin to delete this thread as its quite useless now
