Post render lighting

I saw this -, and thought what the hell, let’s see what I can do with it.

Each of the render passes came in at around 5.5 minutes, and so doing it all in render would take around 23 hours. Instead, I had 16m15s of total render time. Rendering the composite without denoising took around two minutes for the whole anim. Bumped up to 7 seconds or so per frame with denoising turned on. Still, total time less than an hour. Colour me impressed.

I know that the sun should show some travel, but then we are back to 23 hours to pull that off.
