Many of the references in the sample scenes, esp. character animations, are not coming in -- they say Missing.
The up_* animations are great, but I would prefer that the other animations be full body. I.e. run, walk, etc, should be full body animations, like dance.
Why? At the moment, there is no way to have a full body run. I much preferred the 1.2 model animations. That way, I could have an unarmed character run around, and pick up/drop weapons. Then the up_* animations override the run/walk on a higher layer. This works much better. See this video
for an example of what I mean. With 1.3 there is no way to do this. The assumption seems to be that characters will always be armed (which is not always the case) or they will use up_idle (which doesn't show the arm action of run, walk, etc).
Nonetheless, great stuff! Keep it up!
