I’m curious to see what the visual effect ended up being. Any link to an example?

Sounds like a 3D capture rig than visual effects.

  That's correct. I can't say too much about the details. It ended up working really well but wasn't used in production for reasons of internal politics. The guy who had the original idea for the system, a former classmate of mine, later went on to start his own company, Quixel, based on similar ideas.

It sounds like it might have been involved in a process such as this one: https://mobile.twitter.com/AaronCovrett/status/1125409161808838658 https://mobile.twitter.com/AaronCovrett/status/1125409161808...

If you capture an object with light from various angles you can "re-light" it in post-processing. Drop it into different scenes and have realistic lighting coming from different angles. https://augmentedperception.github.io/therelightables/ https://augmentedperception.github.io/therelightables/

    Paul Debevec has been working on this steadily since at least 1999. http://www.pauldebevec.com/FiatLux/ http://www.pauldebevec.com/FiatLux/

    Light doesn't exist, it's made up.

    I recall something like this was done for a presidential portrait a few years ago. https://fstoppers.com/bts/how-smithsonian-created-insanely-accurate-3d-model-president-obama-48294 https://fstoppers.com/bts/how-smithsonian-created-insanely-a...

Sprite Lamp sounds like it may fit the bill as an example, as well: https://www.youtube.com/watch?v=fy3FvPg01w0 https://www.youtube.com/watch?v=fy3FvPg01w0 Given the author's other post about a similar technique going on to be used at Quixel, presumably they were inferring normal maps from lighting data, and later metallic, AO, smoothness etc maps for PBR.
