To edit the DDS for Skyrim in 4.2.10, when I save the file, I use the settings that I myself found experimentally. I do not promise that I will indicate the names of the parameters correctly - these names have already been translated into different languages twice. I chose BC3 (DXT5). The compression mode is "normal" and I can’t switch it. Compression optimization is indicated as "estimated", I left it that way. Should I switch to "uniform"? Turned on "texture generation" and chose the "bilinear method". There is also a “cubic texture” and a “bicubic method”. I suspect this is for normal maps. I think correctly? Or is it for cubic maps? I need to know more precisely which buttons to press.
