Only posting this here since it took us literal months to figure out how to get this product to render somewhat accurately and wanted to share the solution.
It’s important to note that after experimenting with dielectric, films, plastics, and even at one point video textures, what ended up looking most like the real thing was re-creating the laser etched ridges in the film as a very high-resolution bump map, and instead of using view-direction based gradients and dielectrics, using flat textures aligned for different studios differently.
To avoid what I can only describe as a moire pattern in renders, the fine lined bump map had to be tweaked dozens of times to show as little banding at the resolutions we needed to render at. (Pay no attention to the UV wrapping lol)
This product’s holographic texture is similar to a multi-directional lenticular, and reflects different light spectrums highly shaded towards white and pastel.
