Mesh Proxy Settings

C++ Source:

• Module: Engine

• File: MeshMerging.h

Editor Properties: (see get_editor_property/set_editor_property)

• allow_adjacency (bool): [Read-Write] Whether to allow adjacency buffers for tessellation in the merged mesh

• allow_distance_field (bool): [Read-Write] Whether to allow distance field to be computed for this mesh. Disable this to save memory if the merged mesh will only be rendered in the distance.

• allow_vertex_colors (bool): [Read-Write] Whether to allow vertex colors saved in the merged mesh

• calculate_correct_lod_model (bool): [Read-Write] Determines whether or not the correct LOD models should be calculated given the source meshes and transition size

• compute_light_map_resolution (bool): [Read-Write] If ticked will compute the lightmap resolution by summing the dimensions for each mesh included for merging

• create_collision (bool): [Read-Write] Whether to generate collision for the merged mesh

• generate_lightmap_u_vs (bool): [Read-Write] Whether to generate lightmap uvs for the merged mesh

• hard_angle_threshold (float): [Read-Write] Angle at which a hard edge is introduced between faces

• landscape_culling_precision (LandscapeCullingPrecision): [Read-Write] Level of detail of the landscape that should be used for the culling

• light_map_resolution (int32): [Read-Write] Lightmap resolution

• material_settings (MaterialProxySettings): [Read-Write] Material simplification

• max_ray_cast_dist (float): [Read-Write] Override search distance used when discovering texture values for simplified geometry. Useful when non-zero Merge Distance setting generates new geometry in concave corners.

• merge_distance (float): [Read-Write] Distance at which meshes should be merged together, this can close gaps like doors and windows in distant geometry

• normal_calculation_method (ProxyNormalComputationMethod): [Read-Write] Controls the method used to calculate the normal for the simplified geometry

• override_transfer_distance (bool): [Read-Write] Enable an override for material transfer distance

• override_voxel_size (bool): [Read-Write] If true, Spatial Sampling Distance will not be automatically computed based on geometry and you must set it directly

• recalculate_normals (bool): [Read-Write] Whether Simplygon should recalculate normals, otherwise the normals channel will be sampled from the original mesh

• reuse_mesh_lightmap_u_vs (bool): [Read-Write] Whether to attempt to re-use the source mesh’s lightmap UVs when baking the material or always generate a new set.

• screen_size (int32): [Read-Write] Screen size of the resulting proxy mesh in pixels

• unresolved_geometry_color (Color): [Read-Write] Base color assigned to LOD geometry that can’t be associated with the source geometry: e.g. doors and windows that have been closed by the Merge Distance

• use_hard_angle_threshold (bool): [Read-Write] Enable the use of hard angle based vertex splitting

• use_landscape_culling (bool): [Read-Write] Whether or not to use available landscape geometry to cull away invisible triangles

• voxel_size (float): [Read-Write] Override when converting multiple meshes for proxy LOD merging. Warning, large geometry with small sampling has very high memory costs
