Not without the renderer trick. The textures are imported into UnrealEd as 24bit Bitmaps and converted to DXT1 by the compiler, there's no control over the process. I read the Kentie's DX 10 alternative renderer website page and it seems you could override the limit of the Unreal engine by using DD...

Is it possible to modify the Unreal engine to use 32 bit DXT5 or similar textures?

That's because the compression is DXT1, and is fixed at DXT1. It's just what Unreal uses. The only alternative is to forcefully replace the textures through the Direct3D 10 renderer but that isn't a solution for a lot of people. Ultimately, the clouds suck because there's not many colours between d...

Hi, I have found that textures suffer from 16 bit texture dithering/banding problems.
