How to decompress crunched textures

Post by YouDude » Sun Oct 28, 2018 1:47 pm

Hi everyone, I was browsing files from a mobile Unity game on Unity Studio. Some of the textures could not be previewed and If I tried to export them in any format the result would have been a glitchy colorful pixels mess. According to Unity Studio, the file format is "ETC2_RGBA8Crunched", so I googled it and found out that the "crunch" is a type of texture compression for Unity. I've tried several softwares I have, like PVR and Noesis but there seems to be no way to convert it. Do you have any suggestion?

Just wrap your image into a ktx format and unpack it.
