Prefab falls through floor

Hi folks, I’m slowly doubt.

I’m having the following issue:

  • I have a Ground Layer (Cylinder) with Mesh Renderer and Mesh Collider (is trigger is disabled)
  • I have a PreFabs Game Object with a Rigidbody and Gravity enabled

yet the PreFab falls through the floor as soon as it is generated.

I tried applying a physicsmaterial to the ground.

When the prefab is generated, is it already clipping through the floor’s collider? Try generating it with a bit more distance maybe
