convex mesh collider not detecting circular holes inside mesh,convex Mesh collider not detecting circle in mesh

Hi
I have a mesh with circular holes inside it attached a picture but the convex mesh collider cannot detect circular holes inside it. I know there will be a very simple solution to it but I am a beginner and searching for a solution but couldn’t find it. My mesh has a non-kinematic rigid body so I have to use a convex mesh collider.
My mesh looks like this

,I have a mesh with circular holes inside it but convex mesh collider not detecting it.
it take the cube as one cube and neglect cirular holes inside it.
I know there will be very simple solution to it but I am a begnier and searching or solution but couldn’t fing it.

Convex mesh colliders cannot have any holes in them. They represent a single solid convex shape. One solution would be to use multiple smaller colliders for your object. Usually this would be a selection of primitive colliders (box, sphere, etc) that are positioned to roughly match the shape of your object.
