See also [CSGPolygon] for drawing 2D extruded polygons to be used as CSG nodes. [b]Note:[/b] CSG nodes are intended to be used for level prototyping. Creating CSG nodes has a significant CPU cost compared to creating a [MeshInstance] with a [PrimitiveMesh]. Moving a CSG node within another CSG node also has a significant CPU cost, so it should be avoided during gameplay. </description> <tutorials> <link title="Prototyping levels with CSG">$DOCS_URL/tutorials/3d/csg_tools.md</link> </tutorials> <methods> </methods> <members> <member name="material" type="Material" setter="set_material" getter="get_material"> The [Material] used in drawing the CSG shape. </member> <member name="mesh" type="Mesh" setter="set_mesh" getter="get_mesh"> The [Mesh] resource to use as a CSG shape. [b]Note:[/b] When using an [ArrayMesh], avoid meshes with vertex normals unless a flat shader is required. By default, CSGMesh will ignore the mesh's vertex normals and use a smooth shader calculated using the faces' normals. If a flat shader is required, ensure that all faces' vertex normals are parallel. </member> </members> <constants> </constants> </class>
