Hi,

I've this issue. I want to create a white glowing button (in a car interior).
I set the node to be part of an "button" light group.
The "default light group" is only an ambient HDRI source (no group defined)

The render result shows the emitted light in "default light group" and "button".
The most strange thing is, that if I change the emitted color to something else than white - this behaviour disappears and the light groups work as expected.

Having this strange effect made me testing blackbody and lamp spectra that code somehow white light. The result everything that really appears white shows this (let's call it) bug - all specra that are really away from white (e.g. yellowish) work very well.

Does anyone know what's wrong?
Thanks.

Please upload a test scene that shows the problem.

Hi,

I've tried to reproduce the issue, but I failed.
Neither the problem has been solved by V2.1 alpha 4 or does only appear in this special project.
Unfortunatly the data of this can't be shared and I can*t test the same project with the new version as well.
So at the moment we're stucked. I'll come back to this thread as soon as I have some news.
Thanks.
