VRay Light Problem

[AtlJimK]

What is going on here?

Vray light just below the geometry, dbl-sided. The AA is not the problem, works fine in other parts of the image. It is just at the edge of the light.

Thanks.

It actually is the AA but not what you think. Check "Sub-pixel mapping" and "clamp output" under the Color Mapping rollout and it'll fix it. Do a search for these for more explaination, but basically it's because the light source is way above one which is skewing the AA towards white.
