The following code snippet shows the patch needed for the Lip syncing and facial expressions recipe of Chapter 4, Mastering Character Animations. Apply this to the file in your project. If you're applying it manually, the constructor must be added to AnimationEvent, and the following lines of code have to go into the initEvent method just after cinematic.putEventData(MODEL_CHANNELS, model, s);:
int numChannels = model.getControl(AnimControl.class).getNumChannels();
for(int i = 0; i < numChannels; i++){
((HashMap<Integer, AnimChannel>)s).put(i, model.getControl(AnimControl.class).getChannel(i));
}The full patch is:
