Abc Normal Generation Settings

C++ Source:

• Plugin: AlembicImporter

• Module: AlembicLibrary

• File: AbcImportSettings.h

Editor Properties: (see get_editor_property/set_editor_property)

• force_one_smoothing_group_per_object (bool): [Read-Write] Force One Smoothing Group Per Object: Whether or not to force smooth normals for each individual object rather than calculating smoothing groups

• hard_edge_angle_threshold (float): [Read-Write] Hard Edge Angle Threshold: Threshold used to determine whether an angle between two normals should be considered hard, closer to 0 means more smooth vs 1

• ignore_degenerate_triangles (bool): [Read-Write] Ignore Degenerate Triangles: Determines whether or not the degenerate triangles should be ignored when calculating tangents/normals

• recompute_normals (bool): [Read-Write] Recompute Normals: Determines whether or not the normals should be forced to be recomputed

• skip_computing_tangents (bool): [Read-Write] Skip Computing Tangents: Determines whether tangents are computed for GeometryCache. Skipping them can improve streaming performance but may cause visual artifacts where they are required
