I am looking for a way to start rendering a .blend file the moment it is opened. Doing this with a python script that is executed on load is not an option.
That setup will render the image before the interface is fully shown. So basically you're looking at a grey screen until the image is fully rendered in the background.
What I want is that when the file is openend, it starts rendering and you can see the rendering process. Ideally, Blender should quit when the render is completed.
