From the course: Maya: Dynamic Simulations with Bullet Physics

Setting the playback range

The default animation and playback ranges in Maya begin on frame one, as you can see here. The Bullet Simulation is also defaulted to begin on frame1. However, this might result in some errors with this Simulation, as you rewind and play it. Just to insure that, you'll have better performance, and fewer issues, I recommend that you set your playback in Animation ranges to begin on frame 0. And, that way, you'll have a 1 frame run up before the Simulation begins. So, I'll just simply go here and set the first frame of the playback range to frame 0, and that'll automatically set the Animation range to frame 0 as well. And, I'll give myself, some more time here at the end too. I'll set ,the end of the playback range to frame 600. And, I've just set the playback range so that Bullet will perform more efficiently.
