Well, Im here 7 years later and it must be a little late, but lets write it down for those who will google this issue. In my case, dots were produced by some very rare and unreparable bug in 3dmax rasterization pipeline, and I fixed it by 1) reseting 3dmax (File-> Reset ) 2) merging all the geometry from problematic file…
I am struggling with warp projection gizmo. it's inconvenient as hell and always blurry . Does anyone know an easy way to fit projection like UVMap modifier in 3dmax? I hope I may missed it somewhere.
