<br>
All this sounds very interesting and I would probably recommend my users to follow your advice (if I had users yet :-)<br>
<br>
I for myself need to focus on unsolved problems, where the usage of HAnim seems to be a solved problem. <br>
<br>
Only one question: how do you solve MU with HAnim avatars? Can I put Network Sensors into them?<br>
<br>
All the best<br>
