I have modeled a couple of small discs that I would like to use as indirect spotlights. When I increase the surface luminosity for those polygons to let's say 4000-5000% and then render the frame, the luminous polygons look very strange. They seem to be oversaturated with some kind of colour bleeding. I have used KrayAutoParts, checked the option 'Force Indirect Luminosity', and tried the limit dynamic range and Desaturate option within the KrayIndirectRays shader. It does not seem to help.
Is there another option, I am missing. Thanks in advance.
I am sorry, but I have discarded the old versions before I read your post.
What I can say is that it happened because of the sharpening effect of the Mitchell filter.
Next time I will keep them.
