I'm trying to render a single image using a script i have written using blender 2.78c
If i run the script on the default cube it works fine.
If i run it on an existing .blend scene i have loaded i get this error.
I have tried:
bpy.ops.render.render( animation=False, write_still=True )
I've also removed all animations from the scene.
Is there a way to do this?
