Value Type: CollisionFidelity
Description: Determines how similar the collision model of this solid model is, compared to the actual geometry of the solid model.

Collision detection is expensive to compute, so Roblox uses approximate convex decomposition by default to handle collisions with solid models.


Here is an example of an igloo, made with solid modeling.


Depending on the CollisionFidelity selected, this is what the actual collision model of the igloo looks like:

You can view the collision model of a solid model by toggling ShowDecompositionGeometry under the Physics tab in Roblox Studio's settings menu.
