Question about new ASTC WebGL support (PR #11434)

Questions

Hi @AGulev,

I saw your recent PR that adds improved ASTC support for WebGL (https://github.com/defold/defold/pull/11434) and I’m very interested in using it for HTML5 builds.

Could you please share a bit more detail on:

  1. Which browsers/devices this ASTC support actually works on?

  2. Whether there is automatic fallback for browsers that don’t support ASTC?

Thanks a lot!

It depends on the GPU rather than the browser. At the moment, ASTC works on mobile browsers and on ARM-based Macs.

There is no automatic fallback support available.
That’s why we recommend using BasisU as the texture format. It will be transcoded to the best supported format, such as ASTC 4x4 on mobile and BC7 on desktop.
