A problem with light groups

Post by Dez! » Thu May 17, 2018 7:34 am

This error appeared in 2.0rc1, I could not catch it for a long time.
This happens like this:
Make 2 light groups.
In group 1 we put the sun.
In group 2, put the mesh object with the emission.
Now include Lux Core Config - Clamp Output.
After rendering in the compositing window, we see that the node Render Layers in the output of the light group with the sun also contains the glow of the object's mesh.

PS:
If the object with the Emission material is set to brightness and then multiplied by Arrey - its brightness will decrease.

Dear developers, did you fix the problem?
I can not use the clamp because of this. I have to manually clean the white dots.

I opened your file and rendered, without making any changes, and I can't reproduce the problem.
However, I'm using the very latest sources, so maybe the problem was fixed in the meantime.

Please check again.
At me the problem is found out in Path + OpenCL.
In Path + CPU, the light groups work correctly.
In BiDir, too, everything is fine.
