Getting Started

Hi all,
I’m in a trouble and trying since last 30 hours, I have done different experiences and applied many concepts which I learnt through google. But I’m unable to resolve my problem…
The problem is
When I add rigidbody component of any 3d model, like suppose 3d car model, when the game starts, the model falls down continuously. The model is place above the road (y > 0) and road (terrain) is placed at y = 0. Please help me out, what is the problem and which thing I’m missing… thanks in advance :slight_smile:

Make sure your road and car has colliders and they are not triggers.

Also check your layers and check if they have intercollision enabled via Project Settings → Physics → Collision matrix.

Thanks dear, problem is solved :slight_smile:
Also please if possible, guide me regarding following error
Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported in Unity 5.

Enable “Convex” on the Mesh Collider.
Also, I suggest using primitive colliders. E.g. boxing it out because it yields better performance.
