Anyone know what this is and how to fix this?
This is in 3DS Max
missing or no sense making uwv coordinates?
Looks like z-fighting to me
You duplicated the object, one duplicate has a yellow material, the other doesn't. Delete one.
this is z-fighting. definately.
Or you spent a shit ton of time to make a 16k texture with this shit.
If thats the case, gg.
