Unity 3: CCD is not supported for this type of Collider
I'm getting this error message with a couple of new Mesh Colliders I've put into my application. Any idea what CCD is or how I can resolve it? Google search returns some info on Vertexes, but I'm not sure how it applies to my model in Unity.
I am using default settings on the Mesh Collider and it is sitting as a child of a scripted game object.
I have found this information that it has something on Colliders:

Not sure why Unity3 is returning it as an error.
I've attached a picture of my mesh. I know it's pretty complicated for collision, and plan on going back and reducing the complexity significantly (I'm just using the model's mesh, but I really only need the outer rubber piece to detect collision.
$$anonymous$$aking it convex did not fix the issue, it seems to have no negative effects in the game. I admit I'm a complete noob when it comes to modeling, so it's quite possible my model has a mistake.

Set the collision detection mode to "Discrete" on the objects Rigidbody to get rid of the error. Or wait for beta 5, which removes that error message :)

To answer part of your question, in this context I believe CCD is Continuous Collision Detection, which refers to a method of solving collisions, and is part of PhysX in Unity. As for why there is an error I would assume it is not supported for meshes due to complexity/efficiency.
