I found this fun little add-on while looking for ways to make my bowling ball and pins scene more realistic. It really streamlined the whole process.
Basically, it automates the process of animating a rigid body so that the “momentum” can be taken over by the physics engine once the animated keyframes are past. The add-on also shows an estimated trajectory based on other rigid bodies, and all initial variables can be modified (starting position on X.Y,Z, velocity, and angular momentum).
The add-on is called Projectile. It was made by Nathan Craddock, and you can download it here: https://github.com/natecraddock/projectile. There’s also instructions on how to install and use.
Just thought I would share with all of you. Have fun!
