- Flat 2D polygon shape for use with occlusion culling in :ref:`OccluderInstance3D<class_OccluderInstance3D>`.
- Description
- -----------
- ``PolygonOccluder3D`` stores a polygon shape that can be used by the engine's occlusion culling system. When an :ref:`OccluderInstance3D<class_OccluderInstance3D>` with a ``PolygonOccluder3D`` is selected in the editor, an editor will appear at the top of the 3D viewport so you can add/remove points. All points must be placed on the same 2D plane, which means it is not possible to create arbitrary 3D shapes with a single ``PolygonOccluder3D``. To use arbitrary 3D shapes as occluders, use :ref:`ArrayOccluder3D<class_ArrayOccluder3D>` or :ref:`OccluderInstance3D<class_OccluderInstance3D>`'s baking feature instead.
- See :ref:`OccluderInstance3D<class_OccluderInstance3D>`'s documentation for instructions on setting up occlusion culling.

- The polygon to use for occlusion culling. The polygon can be convex or concave, but it should have as few points as possible to maximize performance.
- The polygon must *not* have intersecting lines. Otherwise, triangulation will fail (with an error message printed).
