Hi, Is it possible to have a light illuminate certain objects in the scene but not others ?
Rhino’s renderer is not that elaborate…well the old one was too primitive, and the Cycles path-tracer…those kind of renderers are very “brute force realistic” and don’t go in on the override-every-setting-on-a-per-object-basis thing as I recall from old school CPU renderers like Brazil.
In the future we could make it possible to exclude objects from certain lights, but it is not currently possible.
Could you elaborate a bit? Do you want to lose direct light or all reflected light as well? Are you seeking deliberately to create an unnatural effect? What’s the use case? Do you have a scenario you can post?
