I have loaded an existing puppet into CH Beta, but cannot turn on body tracker

[paulm18875445]

The existing puppet works as it does in CH i.e. facial and eye movements, head and dragable parts etc, however when exictedly loaded the puppet into the CH BETA version. I expected to hit the body tracker to turn it blue and have some fun. The problem I am having is that it will not turn on (blue) but gives me a message that I do not understand, it says "Body tracker requires a puppet with an armed (active) and enabled Body behavior" how do I resolve this please?

I have been a long time user of photoshop but not of CH and I have just converted one of my characters for a kids book into a CH puppet, so it may be somnething I have not done in the commercial CH program.

You need to apply the Body behavior to your puppet. I don't have a machine nearby, but from memory: select the puppet in the project panel, and then click on the "+" in the properties panel Behaviors section and choose Body from the list. Or, from the Puppet panel, make sure the top level is selected (or a group containing all the body parts), and click on the behaviors menu next to the group name to choose Body.
