And, voila, volume rendering saved to png.
However, if I naively continue the script to re-render with new settings:
I find that none of my new settings are reflected in "rendering2.png" -- it's just a duplicate of "rendering.png"! But if I start again from scratch with a new scene, the settings take hold. This leaves me (a new user) scratching my head.
So here is my question: Once you've created and saved a scene once, how do you change scene settings like colormap and camera angle?
