metaball rendering problem

Recommended Posts

Hi all!

I have a scene with 2 areaLights and one environment light (rendering mode: ray tracing background)

Metaballs are copyed on points by copy sop. So i have strange artifacts on some random frames showed on the picture. Its strange, but when i try to rerender this frames this black thing does not disappear. When i convert metaballs to geometry through ConvertMeta sop nothing changes so it defenetly not a geometry problem.

Rop node refract limit : 3 , reflect limit:1, diff limit :1

any ideas?

Just a wild shot . can you add the correct normals after the ConvertMeta sop.

Or put up the geo so we can test

Thanks Mangi, but i think i found solution. After decreasing raytraycing bias (0.0001) the black spots disappeared.
