Cannot save file from LOPS March 23, 2021, 4:52 p.m.

To be frank, I don't feel very motivated to track down a bug in 18.5.462 that is already fixed in 18.5.499

Totally hear you on this, and it makes sense. My big holdup is waiting on 3Delight to build against 18.5.499 (which will happen soon). That's why I put the issue forward with 18.5.462, to at least see if anyone knew what was happening.

The temp file is created, rendered, then cleaned up by the USD Render ROP. So you will only see it if you go look for it while the render is still happening.

I actually watched my temp directory during render to see if it was putting anything in there, and I did not see any files happening. Maybe it was all too quick, but I thought I could spy the process maybe.

Here's a file to check out. I'll note that this file did render and save successfully with Houdini 18.5.499, but not with 18.5.462. Exact same file with no modifications.

About target directory existing: yes, it does. Houdini will even create the directory if it doesn't exist. Just doesn't write the file. My guess is that it actually silently fails to render, as suggested above, for some reason?
