Title: Abnormal Light Sampling
Post by: Polymax on 2013-03-02, 09:52:35

HI!
Maybe you know about this issue, so I'll describe it anyway.
Sampling problem in light of the CoronaLight when the scene has CoronaSky and MeshLight.
This is a serious problem that now limits the use of different types of Lights together.

This is very helpful. We are hunting down this bug for years :) Finally a simple scene that exercises this behavior.

I had this happen the other day, I thought it was a light fitting that was using a material emitter and the light material and casing are sharing vertices, but this looks more like the problem :)

Good spot.
