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…

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

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…

Ah, okay, I wasn't sure if that's supported on GPU but looks like it is.

Cycles Refactor: Replace fixed Tangent input with custom input

Wrong button, sorry.

Cycles Refactor: Replace fixed Tangent input with custom input
