I'm using ATI Compressonator 1.50
I want to compress a .TGA file (24bit) to ATC RGB format.
TheCompressonator.exe -convert -overwrite myFile.TGA myFile.DDS +fourCC ATC
but it convert back to RGB8888.
Using +fourCC ATCI our ATCE (same than ATC but with alpha) works
Also using +fourCC ETC (also produce a RGB8888 DDS).
If I convert from the tool, it works, but not in command line.
Is there a workaround for that ?
