Triangle index element buffer list. Identifies the indices of vertices composing the triangular face primitives.
OptionalmaterialConfiguration attributes representing physical PBR material options matching StandardMaterialOptions parameters.
OptionalnameFriendly name of this model part or submesh.
Interleaved floating-point vertex buffer components. Typically ordered sequentially as: Position (X, Y, Z), Normal (X, Y, Z), and UV (U, V).
Represents a single logical partition or primitive segment of a 3D model. In complex multi-material models, each primitive mesh is stored as a distinct ModelPart to allow different material configurations, vertex structures, or drawing commands.
