Re: [Public WebGL] EXT_pvrtc_sRGB extension to WebGL?

Hey Jukka, could you confirm whether ETC2 sRGB formats work as a replacement for PVRTC sRGB?

FYI: collaboration with Apple's WebKit team is underway to support the ETC1 and ETC2 compressed texture formats in https://bugs.webkit.org/show_bug.cgi?id=197900 . ASTC support is already in WebKit but currently behind a flag; another goal is to take it out from behind that flag.

These devices also support ETC2-sRGB via OpenGL ES 3.0, but the WebGL 1/2 extension is not exposed yet in Safari. Would that work for you? Overall we are trying to focus on having good support for a smaller set of formats (ETC2 on mobile, S3TC on desktop, optionally ASTC) if other formats aren't necessary.

Hi all,

I wonder if there have been any prior discussions about adding
support over to WebGL side?

That would help towards enabling Unity support for linear color space
rendering on Apple iOS devices.
