AssetsTools.NET.Texture fails to decode ETC_RGB4Crunched

[regalialong]

Here's a bundle with a ETC_RGB4Crunched format Texture2D

It contains this image https://commons.wikimedia.org/wiki/File:Staffordshire-bull-terrier-puppy-fawn-2166763.jpg

The problem is really easy to spot in UABEANext's previewer / exporter:

Thanks for the heads up. ETC had been tested before on a few games and it seemed to be working so I don't know what's special about this one. When I have the time I'll look into it.

I've done a lot of code tracing (with a colleague of mine) and we managed to get a successful decode by bypassing DecodeTextureImage and using Assetripper's UnityCrunch.TryDecompress with EtcDecoder.DecompressETC instead, so we think crunch decode may be fucked with these files?

The bundle is from 6000 but it happens on lower versions as well
