After rendering my mesh turn to black, I’m not really understand how the UVmap work in UE4 but after I add the unwrappUVW above UVW Map in 3Dsmax (The5th pic ), it truly lower the overlapping percent. However I still have 15% and lots of mesh overlapping(The 1st Pic). I dont know how to fix the problem directly.
I also show the UV channel_0 (3rd pic) n channel_1(4th pic) in UE4
Please help me to fix the problem, I will extremely appreciate that.
