My goal is to programmatically sculpt a crease into the body of a car. Not much luck so far in sculpting & rendering programmatically, but I have made two observations:
- I run the Blender UI, and enter the following in the Python console:
filename = "sculpt_render.py"
exec(compile(open(filename).read(), filename, 'exec'))
main()
The sculpt happens, it shows in the 3D view window, however the rendered image does not include the sculpt. If I press F12 to render, the new render takes into account the sculpt.
- I run Blender from command line, like so:
home/user/blender-2.83-94b8166a8b05-linux64/blender --background LamborghiniHuracan_high_res_two_bodies_reduced_new.blend --python-expr "filename='sculpt_render.py'; exec(compile(open(filename).read(), filename, 'exec')); main()"
I get this output:
Blender 2.83 (sub 11) (hash 94b8166a8b05 built 2020-03-23 23:59:52)

Segmentation fault (core dumped)
Note that the segfault does not happen if I disable the sculpt (by setting SCULPT_ENABLED = False in the python script).
