I am trying to create an animation programmatically (never using the interface) with Blender. I can take my script and run it in Blender via the "scripts" tab just fine. It creates new scenes, adds cameras, object, lights, etc. I can render the results of the script via the GUI or via command line. But when I run it from the command line, it doesn't actually do anything!
I am using a "blank" .blend file with one initial scene in it with a title card.
Here is the .bat file script (Windows), it uses a python script to create the animation file:
cd\program files\blender foundation\blender blender --background C:\pathtofile\ANIMATION.blend --python CREATE_ANIMATION_FILE.py
It gives me:
found bundled python: C:\Program Files\Blender Foundation\Blender\2.78\python read blend: C:\pathtofile\ANIMATION.blend Blender quit
It runs the script just fine but doesn't change the ANIMATION.blend file at all. Again, if I run the script from the scripts window via the in Blender GUI, it works fine. Anyone come across this?
11) Next step is to build a userpref.blend with Auto Run Python Scripts enabled. NOTE: This is essential because of a bug in blender. Starting blender with -y does not work. Neither does starting blender with a python script setting the autorun flag to ON. It even does not work to compile blender yourself with the WITH_PYTHON_SECURITY flag disabled (OFF). Blender will still not execute the python script. The only way to enable this auto execute is via the GUI. Since we do not have a GUI (or want to install one), we have to build a userpref.blend on a different machine.
