Colliders, Mesh or Box?

Hi, I have a 3D model with zoom and rotation, this model has a lot of small parts, all parts are touchable to generate an action using box colliders.
Many of the parts have different sizes so the box colliders many times overlap one to another making too difficult to touch the desired target.
What should I use? Any help is welcome :slight_smile:

In this case you can use mesh collider. And to optimize it you can create a low poly mesh to match with your actual mesh and use that low poly mesh as your mesh collider shape. This way you can get the accuracy along with less performance hit compared to your default mesh.
