I work on an iMac. I am trying to render a fluid simulation that is very slow, and decided to do it in several batches.
For the first batch, I rendered frames 1-100, and had to stop rendering to perform other operations on my machine. I checked the /tmp folder to verify the result and it looked fine.
Then I rendered frames 101-200 and had to save the blender file and completely restart the computer, because another process made the machine crash.
After restarting, the /tmp folder for Blender didn't contain any rendered files:
I also checked the Trash, but there was nothing in there either.
Were these files completely erased from my machine after the restart? Or were they moved?
I am sorry if this sounds like a noob question, I've never used a /tmp folder with any other app, and I usually create 3D projects and animations that are rendered fast enough by Blender that I don't have to restart my machine during a render.
It's kind of sad if this default location just clears itself automatically upon restart, without even a dialog box warning or asking the user (but Blender's not really good at dialog boxes...). But if there's a way to change/act upon this behavior ("ask before delete" or "never delete tmp folder" options?), I'd love to know.
