@Dr-Sassi thanks for the response. i solved the issues, we’ll kind of. I copied the objects into a new scene and recreated the simulation. It rendered out just fine. I think the issue stems from upgrading my original scene. The original scene had an older version of redshift that didn’t have the pyro volume. For some reason even though I upgraded redshift it would lose the folder link to my cache file during a local render but would keep the link during an IPR.
Sometimes my job is 20% making everything and 80% figuring out the last step that should work but doesn’t.
