Setup automatic rendering of different blender files via python scripting

by Gagandeep Singh   Last Updated April 16, 2019 08:15 AM

I want to achieve following functionality using python in blender -

  1. I want to open blender files located at a given path.
  2. Change textures of some objects in that blender file
  3. Set angle of the camera
  4. Render the scene and save the render at a given location. This will go in a loop for many blender scenes with proper lighting.

From above points I have achieved all points. But my problem is when i open a blender file using following script -

obj_root = pathlib.Path("I:/PythonBlender/first.blend") bpy.ops.wm.open_mainfile(filepath= str(obj_root))

the old file running the python scripts is closed and this new first.blend file is opened in blender. I want my python scripts to keep running and the scenes should load as an addon. and remove the addon scenes after rendering is finished. I also want to know what approach you will follow to achieve the above functionality with proper memory management and loading, unloading of textures and other files after rendering is done.
