Does anyone how to render VSE seperate and and 3D scene seperately in the background mode? is it even possible? In UI render bpy.ops.render renders whatever SpaceType was last active.

Is it the same bpy.ops.render operator with using an active SpaceType?

I tried bpy.ops.render.opengl aswel because thats python tool tip for VSE render image menu item, but it's write_still=True doesn't seem to work.

I want to:

render frames on the 3Dscene

  1. Render frames on the 3Dscene.
  2. Push them to different Channel Strips in VSE.
  3. Export the VSE preview/output at a certain frame to disk or a texture

And I want to do this recursively, dynamically via script in background mode.

Help is much appreciated.

It is not depending on active space. If scene.render.use_sequencer is true, Blender will render from sequencer (VSE) but only if it has image strips.

In UI you can find it here:
