OctaneRender™ 2021.1 RC 3

Hi OTOY Team,

I did not share my gratitude towards this stunning release (considered now, at the time of this reply, "deprecated"). In particular the important fixes.

However, I am facing an obnoxious behavior since this release and any versions higher: on some scenes containing USD assets, my materials (nodes) are no longer applied to the USD geometry node. The imported USD assets is using default materials and my custom materials do seem to be lost.

My current workaround is to have two Standalone instances opened, both different versions and copying/pasting my nodes to plug them back again (using the speed-efficient and useful CTRL + HOLD shortcut as I am assigning materials to a custom assets/shading group nomenclature).
I also have back up files and I am aware that these builds are non-production-safe.

I suspect this fix is the cause behind it:

[*] Updated USD library to version 21.08.

I can handle the extra manual work, however, I would be curious if I could get a confirmation of my suspicion.

Hi Elsksa,

Thanks for the report. I'll look into it. Since you said the behaviour is happening only in some scenes, it would be better if I get that ORBX file. Could you please forward me the scene if you can able to do so.

Thanks,
Vijay

Hi Vijay,

Thank you for your reply. My bad for the poor writing. I did not mean to say "on some scenes". At the moment, I have tried two scenes using USD assets and both are behaving the same. I will try to provide a scene that I can share (ASAP) with some basic geometry primitives USD assets, to open in two different Octane Standalone versions.

Hi Elsksa,

I can able to reproduce it. This started happening after I fixed a bud in loading USD materials. USD can have duplicate material names and it was causing issues in loading and linking materials. After my fix to the bug, Old saved material are not used. You will have to manually relink/redo materials from an old scene. Sorry for the inconvenience. This will not happen again after you relink the materials.

Thanks,
Vijay
