I just wanted to correct a very common misunderstanding that I see around here, even among people knowledgeable with Cinema 4D: that Cinema 4D doesn't export joints to FBX, and that you have to convert your joints to bones before they can be imported into Unity. This is simply not true with R11. Just to make it really really clear: Cinema 4D R11 exports joints to FBX! Got it? Good. The only thing you have to do is manually bake any IK or Xpresso before putting the .c4d file in your assets folder, as baking isn't done automatically when exporting to FBX. I've put up a script on the wiki that does this in a reliable way. It also does some other nifty stuff, like automatically saving the baked file to your assets folder and deleting your controllers so they don't clutter up the hierarchy in Unity. Now stop perpetuating the myth and start using them joints!
