Hi,

I would like to know which export option (photoshop) should I choose so that the file is compatible with the format: R8G8B8A8_UNORM_SRGB ?

Hi @F4ll0ut! I believe the closest you can currently get is by selecting 8.8.8.8 BGRA:

and by enabling “DDS:Use DXT10 Header” at the bottom here:

This will output an uncompressed DDS file using the B8G8R8A8_UNORM DXGI format - roughly similar to R8G8B8A8_UNORM_SRGB, but the channels are in a different order, and the GPU does not automatically convert colors to linear.

(Without “Use DXT10 Header”, it’ll output an uncompressed DDS file that uses bitmasks; this should be compatible with apps that use DDS readers from before DirectX 10 was released.)

Is there a specific app you’re trying to use this file with, if I can ask?

Thanks!

Thanks for your answer. It’s for a texture for the game Starfield that just came out.
