Today, I was trying to import pixel art from MagicaVoxel to Unreal Engine. Import is easy without any problems, but when I try to generete collisions, they are really inaccurate. I get best results with Auto Convex Collision tool. I am exporting models from MagicaVoxel using obj (Wafefront)
format. How to solve this issue?
MagicaVoxel Model
Collisions generated by Auto Convex Collision tool
Inaccurate collider
I tried it in UE 4.16.3 and seems work for me well by default. In Convex Decomposition try to set Accuracy to 0.5
