Collider problem with physics

Unity Engine
1

Hi,

I have a global mesh with inside different part, each part have a collider & rigidbody 3D ( Chunk ), when i shoot with my gun, my bullet have a rigidbody and a sphere collider i add forward force on him like that :

Temporary_Bullet_Handler.GetComponent<Rigidbody>().velocity = BallisticForce * powerMultiplier * Temporary_Bullet_Handler.transform.TransformDirection(Vector3.forward);

But in many many many case, my bullet don’t collide propretly with my chunk and passed through my chunk …
How can i fix that ? I don’t want use Raycast

It happens because bullet speed so fast, so it just jumps over a collider.
There is two solutions:

  1. Raycast
  2. In the inspector of Rigidbody component for bullets, set “Collision detection mode” to “Continuous”
    But static colliders also should be set properly.

In our opinion, raycast is simpler and more reliable solution.
