Now, I don't want to come off as an elitist, but I know a thing or two about computers and how things work. I know that people put ALOT of time and effort into these maps, and to have the UGX mod the way it is, almost like its own section of the game, is unreal. But there's one thing I don't see a lot of. Weapon skins! Some of the "professional" (if you will,) maps done by experienced mappers have custom guns and custom weapons. I know that there is the MOTD, moving, glowing like camo in the UGX mod, but I'm talking about straight camo and skin mods. Many players, including myself, are fascinated by small details, like camos and skins. This may not go for everyone, but I would enjoy just playing stock maps with some interesting camos. Not a fanboy, but I remember when the ZM skin pack was released, and I had a blast with how it all looked. From what I've read, this game engine is a pain in the ass,  but I think if there was an application that allows users to draw and animate their own skins, some people who may not be the best programmers, or mappers, could really show off what they can do. You can also have contests or polls that help pick the skins/camos for the next "big map"

Again, I'm not a wizard on these types of situations, but I kind of know how things work. Take it as you will, but I think making skinning easier would help the community grow and expand to different types of people. I just hope that more people will be able to join the community and see the wonders of UCC.

For the record we had those in our mod before MOTD was even announced

Skinning (or at least the "packs" that you were referring to) is one of the easiest and most outdated ways of modding your map in CoD, which is why you don't see people bothering to do it much any more. It's tacky now because it's so overdone. People are more interested in seeing the guns as they are supposed to look, not ones with neon colors and patterns all over them.

I've never seen a weapon skin pack for CoD that I liked better than the stock textures. IW and 3arch do a good job with their modeling and textures and I've never seen a reason to make improvements personally.
