Hi,
I'm currently trying to convert the attached images to astc.
The settings I have specified is 4x4 and linear LDR for "alpha1.jpg". The tool displays each pixel's value as R = G = B with A = 255, so I specify "Other Options" swizzling before encoding G = 0, B = 0, and A = 0 because I only care about the R channel. Unfortunately, I get "Commandline argument '-esw r000' not recognized". If I remove the "Other Options", it works.....I also tried 4x4 SRGB LDR with Other Options turned off, but I get "Compression stopped"
None of the above configurations work for "alpha11.jpg". Both images work with the solo option of HDR......which doesn't sound right to me. Am I misunderstanding how to use the tool?
Thank you.
Chris, the way ASTC works it makes no difference. Regardless of input format every ASTC output image is essentially RGBA.
gotcha.
