RS OpenPBR renders in IPR, not in Picture Viewer

[room-unit]

C4D 2025.2.0, Redshift 2025.4.0, Windows 11, RTX4090, Studio Driver 572.83
OpenPBR material applied to xpOpenVDBMesher renders fine in Redshift IPR, does not show up at all in Picture Viewer render.
Any ideas?

Hi room-unit,

So far, that would be the first time I've checked my usual source of problem entries.

Does the OpenPBR work with a polygon object for you?

Sorry, I can't reproduce it with similar setups.
I have no current XP version, so I can't even check it here.

We had a similar case with Hair, and the solution was to drag the Hair Render Settings entry above the Redshift entry.

Useful information would be if it renders in Redshift Render View in besides Progressive also in Bucket mode.

However, since this needs direct attention, please check with Tech Support.

Thank you, and sorry for the trouble!

my best wishes

Solved: it was because there was a Cache tag on the Mesher. (I don't remember putting it on there, but obviously I did.) I deleted the cache tag and all became well. Thank you for your input!

Thank you for the reply, room-unit.

This is why I typically ask for a file instead of images. Since I do not have a current Insydium license (Too few questions here to justify it), I did not ask.

My best wishes for your project
