classmethod apply_mesh_bevel_selection(target_mesh, selection, bevel_mode, bevel_options, debug=None) → DynamicMesh

Apply a Mesh Bevel operation to parts of TargetMesh using the BevelOptions settings.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_disconnect_faces(target_mesh, selection, allow_bowties_in_output=True, debug=None) → DynamicMesh

Disconnect the triangles of TargetMesh identified by the Selection. The input Selection will still identify the same geometric elements after Disconnecting.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_duplicate_faces(target_mesh, selection, group_options=[GeometryScriptMeshEditPolygroupMode.PRESERVE_EXISTING, 0], debug=None) -> (DynamicMesh, new_triangles=GeometryScriptMeshSelection)

Duplicate the triangles of TargetMesh identified by the Selection

Parameters:
Returns:

new_triangles (GeometryScriptMeshSelection): a Mesh Selection of the duplicate triangles is returned here (with type Triangles)

Return type:

GeometryScriptMeshSelection

classmethod apply_mesh_extrude(target_mesh: DynamicMesh, options: GeometryScriptMeshExtrudeOptions, debug: GeometryScriptDebug = Ellipsis) → DynamicMesh

deprecated: ‘apply_mesh_extrude’ was renamed to ‘apply_mesh_extrude_compatibility_5p0’.

classmethod apply_mesh_extrude_compatibility_5p0(target_mesh, options, debug=None) → DynamicMesh

Backwards-Compatibility implementations

These are versions/variants of the above functions that were released in previous UE 5.x versions, that have since been updated. To avoid breaking user scripts, these previous versions are currently kept and called via redirectors registered in GeometryScriptingCoreModule.cpp.

These functions may be deprecated in future UE releases.

DynamicMesh

classmethod apply_mesh_inset_outset_faces(target_mesh, options, selection, debug=None) → DynamicMesh

Apply an Inset or Outset to the faces of TargetMesh identified by the Selection, or all faces if the Selection is empty.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_linear_extrude_faces(target_mesh, options, selection, debug=None) → DynamicMesh

Apply Linear Extrusion (ie extrusion in a single direction) to the triangles of TargetMesh identified by the Selection. The input Selection will still identify the same geometric elements after the Extrusion

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_offset(target_mesh, options, debug=None) → DynamicMesh

Offset the vertices of TargetMesh from their initial positions based on averaged vertex normals. This function is intended for high-res meshes, for polymodeling-style offsets, ApplyMeshOffsetFaces will produce better results.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_offset_faces(target_mesh, options, selection, debug=None) → DynamicMesh

Apply an Offset to the faces of TargetMesh identified by the Selection, or all faces if the Selection is empty. The Offset direction at each vertex can be derived from the averaged vertex normals or per-triangle normals.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_polygroup_bevel(target_mesh, options, debug=None) → DynamicMesh

Apply a Mesh Bevel operation to all PolyGroup Edges.

Parameters:
Return type:

DynamicMesh

classmethod apply_mesh_shell(target_mesh, options, debug=None) → DynamicMesh

Create a thickened shell from TargetMesh by offsetting the vertex positions along averaged vertex normals, inwards or outwards. Similar to ApplyMeshOffset but also includes the initial mesh (possibly flipped, if the offset is positive)

Parameters:
Return type:

DynamicMesh
