Blender has a variable you can check for that bpy.app.background

Boolean, True when blender is running without a user interface (started with -b)

  • $\begingroup$ Thanks for your answer. I tested and told returned me False when i tried in the console of my active blend after launched another .blend (in background for this one). Did i have to "target" the .blend launched in background ? $\endgroup$ – pistiwique Jan 12 '16 at 19:29
  • $\begingroup$ The console you type it into will be the foreground blender that is running a gui. If you start another instance in the background from a script then you want that copy of blender to run a script that tests the background value. Try running blender --factory-startup -b --python-console in a terminal then type in import bpy bpy.app.background $\endgroup$ – sambler Jan 12 '16 at 19:47
