I'm currently creating a inventory screen, and was wondering how one would have your character show up next to the items on the screen. I don't mind if the character isn't animated, but that would be a plus. Sorry about this, I just don't have any ideas on how this would be possible. ... If it is possible.
If you mean as a 2D video, that's not possible. But there is a lot of great API to get static avatar images. http://wiki.roblox.com/index.php?title=API:Class/Players/GetUserThumbnailAsync
For a 3D version you can set character.Archivable=true then clone it. Then move and manipulate that clone at will. Play animations on its humanoid exactly like it's a player. All of it should be done client-side.
