Different Physic engines?

Questions & Answers
1

My questing is fairly simple. I am fairly new to the Unity3D engine, a few months, and I would like to use a different physics engine that the Unity engine. I was wondering if you can import an engine like Bullet or Nvidia Physx into Unity3D and use that instead?

Thanks for taking the time to answer.

Unity already uses PhysX, but no, you can’t replace it with another physics engine. You can write your own using scripting or use C++ plugins though.

Please post the code when you get the Bullet engine integrated. LOL.
