Description

TriangleMeshPart is an abstract intermediate class from which MeshPart and PartOperation inherit. It was created to consolidate the management of physical geometry properties between the two sub-classes. It implements the read-only CollisionFidelity.

CollisionFidelity

TypeDefault
CollisionFidelity

This property determines how the collision model of the TriangleMeshPart relates to the actual geometry of the mesh. This property cannot be read or manipulated by scripts during runtime.

See here for a visual representation of the various options.

This property is not replicated. Its interface does not cross the network boundary.

FluidFidelity

TypeDefault
FluidFidelity

Controls which geometric representation the physics engine uses when it computes aerodynamic (fluid) forces and torques for the part. It defaults to FluidFidelity.Automatic, in which the engine selects a representation on your behalf.

  • FluidFidelity.Automatic — the engine chooses the representation; it currently evaluates fluid forces against the part's collision geometry.
  • FluidFidelity.UseCollisionGeometry — fluid forces are evaluated against the part's collision geometry, matching the shape used for collision detection.
  • FluidFidelity.UsePreciseGeometry — fluid forces are evaluated against the part's precise mesh geometry, producing more accurate forces at a higher computational cost.

Because this property has plugin-level write security, it is configured in Studio rather than assigned by runtime scripts.

This setting only affects a part while fluid forces are active for the place, which is governed by Workspace.FluidForces (an FluidForces value that defaults to Default; setting it to Experimental enables the aerodynamic force model). When fluid forces are not applied to the part, the chosen fidelity has no effect.

This property is not replicated. Its interface does not cross the network boundary.

MeshSize

TypeDefault
Vector3

This read-only property reports the size of the part's mesh geometry when it was loaded, as width, height, and depth in studs. It is not affected by resizing the part through BasePart.Size, so dividing BasePart.Size by MeshSize gives the scale factor currently applied to the mesh's visual and physical geometry.

This property is not replicated. Its interface does not cross the network boundary.
This property is read-only. Its value can be read, but it cannot be modified.
