and now that i'm requiring less research and testing, i'm able to make faster progress towards the vision i have in mind.
basically i've got about 5 different camera sets, with their various backgrounds and foregrounds mostly rendered, and all the compositor/layering effects i think i need for the first full length music video.
i've just got a few more models to build for the foreground, then edit the various renders together.
i'll probably end up with several animations that have similar cameras and objects, but with the different lighting effects and color palettes.
after that, i intend to model some tunnel backgrounds.
