rich_lord Posted April 11, 2016 Share Posted April 11, 2016 Hello. Here's two renders. The only difference is that the one on the left has the Render Polygons As Subdivision(Mantra) checkbox on. The one on the left is a much nicer result, except for the black dots that get created uniformly across the surface. Anyone know the cause of these dots? Or the settings I should experiment with to get rid of them? splodge_pb.hip Quote Link to comment Share on other sites More sharing options...
Atom Posted April 12, 2016 Share Posted April 12, 2016 (edited) The problem seems to be with the sphere geometry itself. At the top of your network try creating your sphere using a box instead of a sphere. If you set a box to it's minimum divisions (2,2,2) then immediately follow it up with a Subdivide, it will transform in to a quad based sphere without pole bunching issues. Use the sub divide to increase resolution as you see fit. There is a reported warning on your mantra surface which might be contributing to the problem but swapping the sphere with a box seems to reduce the render anomaly quite a bit.

jrockstad Posted April 13, 2016 Share Posted April 13, 2016 That's a strange one. Do you get the same result using OpenSubdiv instead of Mantra for your subdivision scheme? Quote Link to comment Share on other sites More sharing options...
