Hi,
I am runnig the WHitted Optix samples but the results are rendered with cicular artifacts as can be seen in the link:
How can I solve this problem?
Cheers

Artifacts like these are normally self-intersection issues from shadow rays.
If the example uses a scene epsilon to offset the shadow rays, that is scene size dependent and would need to be increased to prevent the self-intersections of the shadow rays with the starting surface point.
On flat geometry these artifacts are ring shaped because of the radial intersection distance of the surface hit points to the ray origin, here the pinhole camera position, and floating point precision limits.
I changed the scene epsilon and worked perfectly. Thanks for the help! =D
