Blender 2.8 seems not to store custom theme files in scripts/presets/interface_theme anymore. Only the default-themes that ship with Blender by default show up there. I searched my system for the name of my theme but that does not yield any results. So: where does Blender 2.8 store theme files on Mac OS?

You can use this utility file to get the theme file


Generates 'userdef_default_theme.c' from a 'userpref.blend' file.

Pass your user preferenes blend file to this script to update the C source file.


./source/tools/utils/blender_theme_as_c.py ~/.config/blender/2.80/config/userpref.blend
