Can I turn the result of a finished textured mesh in Blender 3.3 LTS into a NIF file and DDS file? I just started learning about the process of making textures with nodes yesterday and I was wondering if it is as viable for making FNV content as making DDS files in Photoshop/GIMP, or Substance 3D Painter.

I wanted to know why it works, and I think it has something to do with the FaceGen software. I want to see for myself but I don't know how to open a Khajiit face in the demo version. I have this csam folder that has Khajiit files in it, and they end in .bmp .egm .egt and .tri, but I don't know how to open them in facegen's 3.34 demo. If I don't need the facegen program, may I have an idea of where to look for how the topic title works?
