  • Module: Engine

  • File: EngineTypes.h

Editor Properties: (see get_editor_property/set_editor_property)

  • build_reversed_index_buffer (bool): [Read-Write] Required to optimize mesh in mirrored transform. Double index buffer size.

  • build_scale3d (Vector): [Read-Write] The local scale applied when building the mesh

  • compute_weighted_normals (bool): [Read-Write] If true, we will use the surface area and the corner angle of the triangle as a ratio when computing the normals.

  • distance_field_replacement_mesh (StaticMesh): [Read-Write]

  • distance_field_resolution_scale (float): [Read-Write] Scale to apply to the mesh when allocating the distance field volume texture. The default scale is 1, which is assuming that the mesh will be placed unscaled in the world.

  • dst_lightmap_index (int32): [Read-Write]

  • generate_distance_field_as_if_two_sided (bool): [Read-Write] Whether to generate the distance field treating every triangle hit as a front face. When enabled prevents the distance field from being discarded due to the mesh being open, but also lowers Distance Field AO quality.

  • generate_lightmap_u_vs (bool): [Read-Write]

  • max_lumen_mesh_cards (int32): [Read-Write] Max Lumen mesh cards to generate for this mesh. More cards means that surface will have better coverage, but will result in increased runtime overhead. Set to 0 in order to disable mesh card generation for this mesh. Default is 12.

  • min_lightmap_resolution (int32): [Read-Write]

  • recompute_normals (bool): [Read-Write] If true, normals in the raw mesh are ignored and recomputed.

  • recompute_tangents (bool): [Read-Write] If true, tangents in the raw mesh are ignored and recomputed.

  • remove_degenerates (bool): [Read-Write] If true, degenerate triangles will be removed.

  • src_lightmap_index (int32): [Read-Write]

  • support_face_remap (bool): [Read-Write]

  • use_backwards_compatible_f16_trunc_u_vs (bool): [Read-Write] If true, UVs will use backwards-compatible F16 conversion with truncation for legacy meshes.

  • use_full_precision_u_vs (bool): [Read-Write] If true, UVs will be stored at full floating point precision.

  • use_high_precision_tangent_basis (bool): [Read-Write] If true, Tangents will be stored at 16 bit vs 8 bit precision.

  • use_mikk_t_space (bool): [Read-Write] If true, degenerate triangles will be removed.
