As a favor, I was attempting to make some (what I thought were) simple changes to the alien_warrior skin, and found myself thwarted by the symbol on the back. Everything I tried to do either didn't work, or screwed things up royally. A simple recolor makes white space show up around the symbol, and that makes just about the rest of the skin white! I'm guessing there's a particular way I need to save the file, but I haven't figured it out yet. I feel like I'm overlooking something simple, but it could just be that I'm too simple to do it right. A little help would be appreciated.
Are you changing the logo texture or just the skin?
If it's the logo, check your alpha channels. I just ran a quick test in photoshop and character tool and removed the logo via the alpha channel. After that, it was just a matter of changing the alien skin and there was no distortion.
I suppose you could also try to remove/change the logo texture using Nifskope, but that's over my head.
Hope this helps.
