Running some experiments here and I'm 99% sure the issue is application side in how the blend equation is being set up. I've uploaded a test program here which will...

Things start to look wrong for the experiments where things are mismatched. ### Scenario three: Pre-multiplied sRGB input with post-multiplied blend Premultiplied texture (use `-pp-premultiply`), blended with normal blending (`(dst.rgb...

FWIW I think you should be ticking the "Premultiply alpha" tick box in the spine exporter and in the runtime as per your usual content workflow, and NOT using the...

No worries.

Closing, as no activity and it looks like an application-side issue. Please feel free to reopen if needed.

I get warnings when compiling astcenc using clang++-9 and clang++-12 on Ubuntu 20.04 (WSL).

Can confirm it's C++ (clang++) for my builds. Team policy is to go strict on warnings, so we're compiling with `-Wall -Wextra`. Testing locally on clang++-9 it's the `-Wextra` which...

> The main problem is the ASTC specification is so complex that some block unpackers wouldn't always catch invalid blocks The astcenc block unpack should be standard-conformant - returning either...

A few issues were fixed during the development of the 3.x series, so there have definitely historically been cases where it's not been doing the right thing here, but for...

There are two different aspects to perceptual metrics - chroma bias, and gamma bias. The current `--astc_perceptual` mode only corrects for chroma bias, and should be valid for both sRGB...
