FMeshView | Unreal Engine 5.8 Documentation

API > API/Plugins > API/Plugins/MeshPartitionEditor

A constrained view of an FDynamicMesh3 which is provided to MegaMeshModifierComponents when they apply modifications. The view is constructed to only provide data within a specified bounding region to ensure modifiers only modify the base mesh within their bounds.
