(open) [HOU-3183] Exclude object from reflection \ refraction in other objects

V-Ray V-Ray for Houdini General

Hi,

How do I exclude an object from reflecting and refracting in some other objects?

I have a “reflection card behind” a glass bottle and I’d like it to affect only the bottle and the liquid but not the rest of the scene.
It was controlled per object in 3ds Max via Trace sets. Can’t seem to find this option in houdini.

We use standard Houdini controls for that, there are “Reflection Mask” and “Refraction Mask” parameters under “Render” → “Shading” tab.

Thank you Andrei,
Adding objects to the list does not do anything by itself. Do I need to turn something ON in Vray settings to make it read these parameters?

OK, it works on CPU but does not work on GPU. Is it a bug or not ready yet?
