Hi, On our render farm (Linux based), I’ve noticed some machines sometimes render old versions of a V-Ray 3 scene. I’m not sure if this is required to reproduce this behavior, but we’ve only noticed this when mayabatch region rendering (splitting up one image onto multiple machines); render … -reg…

Newer version of V-Ray already deal with this issue. They append the PID of the process to the filename. The stable 3.0 build should have this feature. Also 3.0 night builds where rev >=24721.

We are already running a new-ish stable build 25208 of V-Ray 3. But I was unaware of that the PID was appended to the process name. I’m going to look into that. But would it be useful if V-Ray indeed removed any vrscene_*.txt files from the /tmp folder prior to rendering? Thanks!

Hm, yes. You’re probably right… we’re not the only ones running only 1 process of V-Ray on the same machine… :slight_smile: So basically, what I could do is when my wrapper script is finished executing the V-Ray render, it could simply delete any vrscene_.txt files which match the PID of the proces…

In fact it is not the PID we’re appending, but some random stuff. Sorry for misleading you. Is this problem easy to reproduce on your side? And these vrscene file are important only if you’re using V-Ray’s DR.

I noticed that this was not a PID just now… but if these vrscene_*.txt files are only needed for DR, then it doesn’t matter in this case as this was not a DR render. Does V-Ray at all store any kind of local copy of the scene file to be rendered somewhere and is it possible that during a Maya crash…

[image] Material Override Exlusion Does V-Ray at all store any kind of local copy of the scene file to be rendered somewhere and is it possible that during a Maya crash, this scene file can be “left behind”, and re-used by a new Maya instance? Usually a .Vrscene file is saved in the “tmp” fold…
