This is a paid asset, but we’ll share Non Convex Mesh Collider Free for you. Enjoy!!!
Non Convex Mesh Collider v1.0
Compatible with all Unity Versions starting with Version 5.
Super easy to use.
Solves the ‘Non-convex Mesh Collider with non-kinematic Rigid Bodies are no longer supported in Unity 5.0’ problem.
Works with every mesh.
Is blazing fast.
The script can be added to a gameobject at runtime or in the editor.
Generated colliders are storable as part of a prefab.
Allows using physics controlled objects of any shape, also non convex (=concave) ones, together with a Rigidbody, which has IsKinematic turned to false.
Works by creating compound colliders that approximate the shape of any mesh.
Save tons of time compared to creating colliders manually, let a script do the work!
