Generate mipmaps on GPU for BC7 format fails to produce correct mipmaps #313

Open FilippoLeon opened 5 months ago

FilippoLeon commented 5 months ago

I am facing a problem generating a mipmap chain on the GPU for BC7 files.

I am using the following command to produce mipmaps for a BC7 texture:

compressonatorcli.exe test.tga test.DDS -fd BC7 -EncodeWith GPU -GenGPUMipMaps -NumThreads 1 -miplevels 16

This produces incorrect mipmaps.

This command works as intended:

compressonatorcli.exe test.tga test.DDS -fd BC7 -NumThreads 1 -miplevels 16

test.zip

(The same result is obtained with the embedded apis)

Am I doing something incorrectly or is the generation not supported?
