Hi! Question, not sure if it is possible… I have 5 nail polish bottles, with a black shiny cap.
I want these caps to be reflected by the bottles, but not between each other… is that possible?
Thanks
Could render in 2 passes. Tops, then bottoms. Or just 'shop it if it’s just a still.
There’s a new feature in the right click > Vray properties per object called trace sets which you can use to control what can reflect what.
Yes, I saw that, thanks! But it does not work, I mean, it should work, it let me select some objects to put them on the exclude list, but then when I hit OK, the setting resets and the objects do not stay on the exclude list.
Did you click the little arrow button that points to the right?
Yes of course I did. It is broken, I posted it very detailed into the problems section and also a scene with the issue, and reproduced it with a scene from scratch too… 100% broken.
Which build of vray are you using? 3.0 / 3.1 / 3.2 / nightly?
3.20.02 I didn’t know of nightly versions of Vray… how can one get into that? I’m already testing the nightly versions of Phoenix.
Ugly renders and scene - trace sets on and off in layers:

You’ll need to do it in passes or you might see topless bottles in the reflection like you can see in John’s.
you are right… but because of the angle I had the camera I was not seeing the capless bottles on the few that worked.. it would be nice to have it fixed thougth 
very usedul tool if works.
