My new (successful!) testing DDS for Skyrim in 4.2.10.

[Banderlog]

  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?
  As a result, textures in the game work. There is no longer a problem with maintaining transparency in textures! All these issues could be resolved very quickly and without stretching the pleasure of our communication on many topics with a hasty closing of these topics.

We could have resolved this much more quickly if you had simply upgraded to 4.2.10 when you were told to do so. Now you have, and the DDS textures are working as expected. This is exactly WHY we kept telling you to upgrade paint.net.

 

I'm glad you have found a solution to your problem. Your other questions are best re-posted in the DDS plugin thread.
