>>2569842To be able to edit dds files VV uses, you need to be able to open the Transparency in the files as Alpha Channel, which I don't think
paint.net can do.
Not every texture needs this, so some should be still editable in
paint.net but not all of them (hair, skin definitely need the Alpha Channel)
so it's probably best to look for a totally legal photoshop install on the net.
The settings I use in photoshop are like this
Diffuse with Alpha: BC7 8bpp Fine sRGB (export Color+Alpha)
Diffuse without Alpha: BC7 8bpp Fine sRGB (export Color only)
Normal/Specular: BC7 8bpp Fine Linear (export Color only)
