Mantra flicker on far away objects Oct. 22, 2018, 11:05 a.m.

Try setting the Raytracing Bias parameter on the Mantra ROP (Rendering > Shading > Raytracing Bias) to a smaller number. It defaults to 0.001 so try 0.0001.

I wonder if it could also be a transform deform issue with precision in the crowd agents. Maybe the cap's transformed slightly differently than the head skin causing the two to interpenetrate.

Is the cap placed as a prop in the agent or is it part of the base deforming mesh shape?

Btw the agents look awful cute.

How many primitives?

Fun exercise trying to build surfaces lazily with a one SOP solution.

Bjorn is correct in that you should be throwing a Ray SOP in there before you extrude.

Here is a few different tries of surfacing the curve faces with varying degrees of success. I thought the new PolyFill SOP with Quadrilateral Grid option would do it but I had to point jitter to try to fix some shapes and still. Meh…

In the end Remesh SOP with adaptivity enabled did a very nice artifact render free job.
