CoronaMtl Self illumination Multiplier

[telemix]

Self illumination Multiplier does not increase the brightness in CoronaMtl. But, it works correctly in the CoronaLihtMtl.

It's Self illumination Multiplier issue? Or automatic multiplier threshold in CoronaMtl?

Hi, this comparison does not make sense as self illumination and light intensity are two completely different things.

You should never use self illumination as a main light source for your scene.

Please see this article:

The reason why self illumination produces darker result, is because it is clamped by max sample intensity.
MSI: https://coronarenderer.freshdesk.com/support/solutions/articles/5000515636

You should get identical results if you set MSI to 0, but both setting MSI to 0 an using self illumination for strong light is not correct.
