Blender has a particle physics component which defines the way that
esoteric substances like smoke or fluids (or, by extension hair, fur
or blades of grass) behave. The calculations are baked and cached on
disc.

This is separate to rendering which, in blender, uses a number of
different rendering components, some of which can use the GPU or the
CPU.

I can't get the CLI to run on my machine, though. When I start Blender
I get an error message "OSError: Python file
'/opt/blender/reset_excepthook.py' could not be opened: No such file
or directory". When I run Blender's GUI, there isn't an issue and it
doesn't affect the program. However, if I try to start Blender without
the GUI, it aborts.
