Hi...
All you need to do is make sure you have "Rigid Body Simulation" turned ON on the top toolbar, then record your bullet physics animation, when happy with the results just turn OFF "Rigid Body Simulation". This will bake the animation to the timeline where you can play it back and render to video.
Regarding the comment that "
Reallusion seems quick to take the ,but offer little or no support", can you explain more about this. We have a dedicated support service who will ALWAYS reply and do their best to resolve any issues you may be having. Have you perhaps had a bad experience with support which has made you feel this way?
