I’m having trouble animating a model using this system. In the map.create method, I’ve added the following code after the self.processBranch call:

		mNodePath = Actor.Actor("legs.egg",
                                {"walk": "legs-Walk.egg"})
		mNodePath.reparentTo(render) 
		mNodePath.setPos(-10,-10,5.5)
		mNodePath.loop('walk')

The model shows up fine, but the animation doesn’t play. The model is animated if I put it in the walking panda tutorial though; so I know the files are fine. mNodePath.getNumFrames(‘walk’) is returning 21 frames, which is correct; so I’m not sure why it’s not actually doing anything. Does the loop call need to be done at some later point?
