I getting some odd render errors. Little white dots:
This is coming from a VraySphere light. If I disable the light the dots go away. However if I turn off "affect diffuse" and "affect specular" they remain(!). These artifacts change with a moving camera at every frame, flickering on and off. I tried increasing the light's subD from 8 to 64 but this had no affect.
I thought it may have something to do with the render settings because before I was getting buzzing in the texture in those areas and so I increased the quality in the render settings, using the Nederhorst method (adaptive DMC, min sub 2, Max 25, thres .005).
If I switch back to adaptive subdivision in the globals the dots go away (but then I get buzzing in the animation there). If I keep adaptive DMC and set the min SubD to 1 (not 2) and raise the threshhold from .005 to .1 the dots also go away. This seems odd, because it would appear that worse settings are giving better results.
If I switch to a Maya spot light the problem is gone. So this appears to be a problem particular to the Vray lights. Weird.
Some side notes:
1) ray traced soft shadows (from Maya lights set with angle) are not showing up in IPR.
2) how doe one make a soft shadow with a vray light? I tried increasing the radius, but this did not seem to have any affect on the shadow (or at best a very negligible one).
thanks!
