I've used a few of the other Unity based environments and I'm very happy to have complete control over the avatar's appearance in it. Do we know why we are restricted to a small subset in 3DXChat? Is it a licensing or a technical one? It goes without saying I'm looking forward to more customization options at some point. I'm also aware that most wont figure it out so including the Unity presets will go a long way to helping people with a more complex set of tools.
