This property determines how the collision model of the MeshPart relates to the actual geometry of the mesh.

Note, this property cannot be set by a script during run time as the geometry cannot be recalculated.

In situations where the collision model of a mesh is unimportant, for example when using small MeshParts, developers are recommended to set CollisionFidelity to ‘Box’.

How does CollisionFidelity work

Enum/CollisionFidelity has three options, the results of which are demonstrated in the image below.

Collision Fidelity

Developers can see a visual representation of a MeshParts collision model by enabling PhysicsSettings/ShowDecompositionGeometry
