Cycles: Add thin film iridescence to Principled BSDF

. . . I'll put something together.

I've been looking forward to this for a week now --…

Build: Don't use bundled zstd for blosc

Hi, thanks for the info and for looking into it! This isn't urgent or anything, the PR where I wanted to use the multithreading support has many other issues 😅

I mostly figured I'd open this…

Cycles: Add thin film iridescence to Principled BSDF

Yes, I can think of a few cases:

  • Reflection with thin film IOR < bulk IOR
  • Reflection with thin film IOR > bulk IOR
  • Transmission with thin film IOR < bulk IOR
  • Transmission with film IOR…

Blend files with a lot of Shape Keys aren't compressed efficiently

Okay, some more info: I've got an implementation of this working, and it indeed delivers the expected 25MB file size.

However, all implementations that I've thought of so far are a regression…

I believe I found what's going on here.

In the compression code, there's a tradeoff on chunk size: On the one hand, you want chunks to be as large as possible so the compressor can find…
