BC7 and DX: Problems when using different encoders

Open andre-ferreira opened this issue 5 years ago • 2 comments

Hello!

I am having a few issues when trying to use the GPU method to encode to BC7, the alpha channel seems to get corrupted:

The rgb channel looks okay. The image is an albedo texture with the height packed into the alpha channel (above)

Thanks!

@andre-ferreira Hi, The BC7 codec for DXC is using a DirectX Texture shader as a temporary for a new Compressonator BC7 codec that is been developed. I will take a look to see if this issue can be resolved with what is in the current release.

The OpenCL version is the Compressonator Codec is been coded into DXC.
