Hi everyone !

I'm currently learning Solaris and I'm trying to illuminate an interior scene. To avoid pure dark (and pure dark light artefacts...) I'm trying out to create a dome light that fills the whole scene just a bit and then get the darkness I want at the compositing step.

I don't know if this is the right technique, but I'm trying to create one dome light for each element of the scene. Theses dome lights may illuminate only one element of the scene and ignore the rest (fortunately, there's only few elements in my scene).

I tried to use the light linker but it seems not to work... Do somone knows how to do that ? Or maybe a simpler technique ?

Light linker is the right tool for setting up light linking... I'm not totally sure I understand what is wrong/unexpected about the result you're getting, but I'm guessing maybe you're surprised by how dark everything is? My guess is that it's because even objects that aren't lit by the dome light will still block the dome light from illuminating other objects. In which case the right solution might be to set up shadow linking so that none of the objects in your scene cast shadows?

Thanks for your suggestion ! I found the answer by combining both illumination rules and shadow rules.

I took a screenshot where I illuminate only one element (the pillars) of the scene. It seems to evenly illuminate just as desired for the compositing pass.
