Refraction/Reflection of MatID seems to be broken in vray 3.6

HI,

could it be that the refraction and reflection of MatIDs is broken in vray 3.6 ?
I used it some time ago, cant remember which version of vray it was, and there it worked like a charme.
Below is my setup. maybe I mixed something…

Thanks for any help,
Markus

PS: I also tested it in a new file and got the same problem.


It looks it works fine here with 3.60.03.
Here is my attempt to rebuild that scene: http://ftp.chaosgroup.com/support/scenes/multimatte.max

hmmm, ok i was using the VrayMtlID RenderElement. There it doesnt work. With the MultiMatte it works.
Any reason why the dedicated Vray render element isnt working?

It’s an integer render element and we can’t propagate it. I think there is an option to treat the values as colors and then it should work.

Best regards,
Vlado
