Hi @y2keeth, it looks like you're trying to convert a compressed image directly to a different compressed format. This isn't a feature that is broadly supported in Compressonator at the moment.
It is possible to convert textures between BCn formats directly as of version 4.3 (like BC3 -> BC7 for example), but not for other compressed formats.
ok
any info about RXGB dtx5 uncompressed?
ok
any info about RXGB dtx5 uncompressed?
@y2keeth The DXT5 RxGB format can be converted to any uncompressed format like RGBA8888 using Compressonator. The results might look a bit weird since the DXT5 RxGB format is a swizzled format where the blue channel and alpha channel are swapped.
what is the x channel in RXGB?
@y2keeth The "X" in RXGB is a stand-in for the alpha channel. As for why it's an 'X' instead of an 'A', I'm not totally sure. My guess is that for this format the actual contents of the alpha channel were typically not that important.
ok thanks
RXGB with the argb_8888 compression is that possible?
