I need to know how to make my Rigidbody kinematic

In this tutorial he references a collider that is no longer supported in Unity.

Could someone tell me what I need to do to fix this error?

I’ve aleady payed the *$6.30__*__ for this collider. I’m unsure how to use it, though. I’ll check the site, but if anyone already knows how then I wouldn’t be against you sharing that information.

Yep, I’m requesting a little guidance making the Rigidbody kinematic.

Just check iskinematic on the rigidbody.

Unity is telling me “Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported in Unity 5.”. How do you all think I should respond?
