Excluding lights to reflect on specific objects

It would be very helpful to exclude objects or materials from reflecting specific lights.

The experimental feature ray mask (utility node) should do exactly this.


But I haven’t an example right now, ‘cause I wrote this with a mobile.

Marco, I will look into this. Thanks for the hint
nonetheless this already sounds more complicated in the set up than just selecting a certain light and say exclude certain object :)

Hi Marco, the ray mask node can exclude a material from the reflection or GI, but not from a specific light. If you like to exclude just one light from a particular object in the scene - it isn't possible in KS.
Light linking is very usefull on complex shots like watches or car interiors.
