Wish: Material ID through glass

[Micha]

Hi,

it's a very old wish and maybe it's possible to get it working for the new release - could it be possible to enable refraction transparency for the material id channel? Often I render watch designs and I like to fine adjust parts in post work, but the current material id doesn't show the material id behind the glass.

Hello, Micha,
What you described is not possible.
To achieve the requested result, a second render (quick one, lower quality) needs to be done and the obstructing object/layer either hidden or cut (VRayClipper).

Kind regards,
Peter

OK, Thank you for feedback.

You can set the glass Refraction/Affect Channels to 'All Channels'
This way the Material ID will work with transparency (in a way).

Sounds great. I will discover it at my next VfR3 test round. (At VfR2 I don't got it working.)

Thank you.
