People are putting out a lot of good sci-fi uniforms for M4 and V4. Too bad it seems almost worthless, because almost nobody will put out a version that matches both M4 and V4. Unless you want to dress your sci-fi characters up in star trek uniforms, you're pretty limited in what you can do.
And this, really, goes for any and all uniforms. They're no good to those of us trying to do story-telling artwork if you've only got one or the other.

Davo's Shard armors were the last good ones that I'm aware of. There's those and some of the Xurge armors.
Can anyone out there do full uniforms with rank insignia, some color variations, etc., for both male and female characters. I'd be happy with M3 or M4, personally. Heck, you could even make them textures for the shadowdancer outfits...or just use the M4 and V4 bodysuits! Those are already multipurpose pieces of clothing..they'd work fine. Just do a non-star trek, quality texture for both.
Something along the lines of Porsimo's starship crew uniforms, plus some rank pins maybe, and that'd be perfect, and you'd sell buttloads of them if the quality is good and there was some texture variety.
