In one scene I have two seperate FileOutputNodes and I want different color depths and file formats for each.
In the Blender GUI this is simple. You can press a FileOutputNode, then press N. Then the Properties panel shows and you can change the image settings for each node.
How do I do the same through the python API? I tried creating seperate bpy.types.ImageFormatSettings for each node, but unfortunately that attribute is read-only.
In particular, I want one node to have Open_EXR, 16-bit RGB; the other PNG 8-bit RGB.
I know I can create two seperate scenes and set the image settings for each scene, but I'd rather have one scene (because that's less code).
