I have a design I have been working that generates files for many animations called animate.scad.   I had one large data file to generate many different designs and it was making the animation generation script run rather slow.  So I created a script that will find the data for the particular design I want and save that to a single file called animation_data.scad.  Now when I run the animation generation script to generate animation images it runs pretty quickly.  The problem I have is that when I run my script to get the data for a different design and run the animation generation script it outputs blank images.  If I load the animation_data.scad in the OpenSCAD gui and do not make any changes and just save the file and run the animation generation script again the images are generated correctly. Ideas of what is causing this? Some kind of caching issue in OpenSCAD?

Some kind of caching issue in OpenSCAD? The cache is something I should get in the habit of clearing when I am fine tuning a size by less than a percent or so. So I get bit when the print doesn't have the trim I did to the src 6 hours back. Creates a lot of muttering.  You get good, or bad at that when you've spent 35 years keeping a tv station on the air. News folks can screw up $30k worth a cameras in a heartbeat. And blame me when they are the ones who ran a fancy zoom lens into a door frame.  Isn't it supposed to bounce? I actually got that question once.  She got an education right quick.   And her tenure in front of the studio cameras was a bit less than usual.

I wasn't meaning if there was a bug with the cache more of the way because of how I was doing things. Is there a way to clear the cache through command line?

I am trying not to use the GUI for this, doing everything from command line. I only opened the data file in the GUI to see if it had something to do with the cache.

I only opened the data file in the GUI to see if it had something to do with the cache. Unless it has snuck in while I wasn’t looking, there is no cache that persists from one invocation to the next. That means that for the CLI the only cache is inside the model, caching the results of rendering multiple instances of the same subcomponent.
