yttriumhow are you editing these vtfs? can you pass me the original file and your new one?
I'm editing the VTFs as PNGs in Paint.NET then using VTFEdit to convert them from PNGs back to VTFs.
If you need to take a look at the original VTFs, I have the three of them right here:
And my retextured version is right here (I made two versions, one with the "demo_kilt_color" name and the other with the "demo_kilt_blue_color" name, although they are exactly the same version. I did not touch the original "demo_kilt_normal")
