Tuesday I hosted a talk about iridescence and anisotropy for glTF materials. Went well I thought, and good to hear people's questions. https://www.youtube.com/watch?v=PyMgrV8BErY
This one uses counter-rotating Depth and Normal maps, for a moire like distortion effect which aims to obscure the fact that it’s using rotating UVs to distort the refraction to fake something like a heat refraction effect.
Nice! The previous one was a lot more obviously rotating, making it look like a clear liquid on top, swirling around. This one looks really good though
Working on cleaning up a CC0 car model, to make a showcase asset to demo glTF materials. A gazillion nodes to clean up, bad transforms, all kinds of fun things to fix.
Anyhow, early materials test with the glTF thin film shader...

Found the original, it’s in the Huntington!
