Hello. I would like to edit some normal maps for the official vehicles, however whenever I try to view them in SlowView I get an error. Also if I attempt to open the file using Paint.NET, I just get an error and it won't open it. Does anyone know how to solve this?
DDS 3DC are not exactly meant to be imported/edited. What you could try is loading one of them in Blender UV/Image viewer, then save again in another format (like PNG).
That seems to work nicely, thanks! Anyways, the problem seems to be that BeamNG's normal maps use BC5/ATI2 compression, whereas Paint.net and SlowView only support up to DTX5. I'll install GIMP which should allow me to save the texture in BC5 format.
3DC/ATI2 aka BC5 https://en.wikipedia.org/wiki/3Dc Depends on the software you use. Some just call it 3DC, others BC5, but it's the same at the end.
