Is there something like cookie operator for lights? I would like to extend the reflection of one light by adding another light, however in the place where they meet, the light reflection is doubled. Is it possible to reflect second light only where first light is not visible?

Hey mikolaj,

On your light that you DON“T want reflected, in the parameters, there is a field called ‘Contributions’.
Click the plus sign and select ‘reflect’ in the field for ”Component 1'.
Deselect the check box to disable it. See attached pic.

Hello Matthew,

I would like to have both reflections, however in a place where they intersect, I would like to have only one light reflection visible. If both reflections are visible in intersection, it is just too bright.

Ah, ok.

Would creating geo lights be an option, just for reflection?
Create the shape you need as geometry with the same settings as the regular lights and in the same place, but only have the geo lights in reflections, and the other lights not?

Matt.

It was very hard to light it properly, because I wanted to light the interior of a tube. I ended up blending two renders in Photoshop. Thank you for your time and will to help me, Matt.
