Glowing corners - solution

HI, Crayox, LC retrace is inside SR options panel.
you can switch on/off (he value is not managed by SR at this moment).

if you want, you can set it ON inside SR options, then, use the ">>Save Actual SolidRocks settings as default<<" to force it for each new scene.

You can also edit directly the solidrocks.ini file if you want.

nice pic btw !

you walls were very thin, no ?
this problem heppens very rarely with "real" sickness on walls and roofs. It happens mainly if there's only planes for roof, for example. And/OR if secondary ray bias is <> 0.

note : as far as i've seen, the LC retrace is involved at rendertime (beauty pass). And it affects significantly rendertimes ! (10/20 %)
That's why it's off by default.

but you can make it default if you need.

that's nice to speak around this feature. it's rarely discussed.
It have great effects as well on LC samples wich are behind refracted materials.

In your case you can also consider (if thin geomtry) to activate, too, the check sample visibility of irradiance map.
