Flickering does not occur in mesh extracted from 3dmax, but this occurs in mesh extracted from blender. Do you know what the problem is?
Hello GKmonkey,
it is hard to see flickering in an static image. If you could provide a gif/video of the problem that would be great. Also a picture of the plain mesh in Blender would also help pin down the problems and give the help you need.
(I use meshes from Blender in UE4 myself)
flickering with WPO usually comes from the object bounds not being correct, rather than anything to do with the mesh - try scaling the mesh bounds up a bit to see if it fixes the issue
