Portal material doesn't show up in ID pass

[zboog]

Is it a bug or a feature that the portal material doesn't show up in the ID pass?

Octane is now an R&D render engine for our studio even though it used to be a production render engine, and one of the big reasons is how different the support is from other renderer engines. For instance, we've never had a post on the Redshift forum that didn't get answered.

Hi zboog,

I'm looking into this now. Sorry for the late reply.

EDIT: As in the standalone the portal material is not shown in the material ID pass. This is due to its nature as a "support" material for raytracing in difference to the classical materials.
So yes, it is intended.

Best,
Kai
