Mesh merging settings

C++ Source:

• Module: Engine

• File: MeshMerging.h

Editor Properties: (see get_editor_property/set_editor_property)

• allow_distance_field (bool): [Read-Write] Allow Distance Field: 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.

• bake_vertex_data_to_mesh (bool): [Read-Write] Bake Vertex Data to Mesh: Whether or not vertex data such as vertex colours should be baked into the resulting mesh

• computed_light_map_resolution (bool): [Read-Write] Computed Light Map Resolution: Whether or not the lightmap resolution should be computed by summing the lightmap resolutions for the input Mesh Components

• create_merged_material (bool): [Read-Write] Create Merged Material: Create a flat material from all source materials, along with a new set of UVs. This material won’t be applied to any section by default.

• generate_light_map_uv (bool): [Read-Write] Generate Light Map UV: Whether to generate lightmap UVs for a merged mesh

• generate_nanite_enabled_mesh (bool): [Read-Write] Generate Nanite Enabled Mesh: Whether to generate a nanite-enabled mesh

• gutter_size (int32): [Read-Write] Gutter Size: The gutter (in texels) to add to each sub-chart for our baked-out material for the top mip level

• include_imposters (bool): [Read-Write] Include Imposters: Whether or not to include any imposter LODs that are part of the source static meshes

• lod_selection_type (MeshLODSelectionType): [Read-Write] LODSelection Type: Which selection mode should be used when generating the merged static mesh

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

• merge_equivalent_materials (bool): [Read-Write] Merge Equivalent Materials: Whether to attempt to merge materials that are deemed equivalent. This can cause artifacts in the merged mesh if world position/actor position etc. is used to determine output color.

• merge_materials (bool): [Read-Write] Merge Materials: Whether to merge source materials into one flat material, ONLY available when merging a single LOD level, see LODSelectionType

• merge_physics_data (bool): [Read-Write] Merge Physics Data: Whether to merge physics data (collision primitives)

• nanite_fallback_triangle_percent (float): [Read-Write] Nanite Fallback Triangle Percent: Percentage of triangles to reduce down to for generating a coarse fallback mesh from the Nanite mesh

• output_u_vs (UVOutput): [Read-Write] Output UVs: Whether to output the specified UV channels into the merged mesh (only if the source meshes contain valid UVs for the specified channel)

• pivot_point_at_zero (bool): [Read-Write] Pivot Point at Zero: Whether merged mesh should have pivot at world origin, or at first merged component otherwise

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

• specific_lod (int32): [Read-Write] Specific LOD: A given LOD level to export from the source meshes

• target_light_map_resolution (int32): [Read-Write] Target Light Map Resolution: The lightmap resolution used both for generating lightmap UV coordinates, and also set on the generated static mesh

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

• use_texture_binning (bool): [Read-Write] Use Texture Binning: Whether or not to calculate varying output texture sizes according to their importance in the final atlas texture

• use_vertex_data_for_baking_material (bool): [Read-Write] Use Vertex Data for Baking Material: Whether or not vertex data such as vertex colours should be used when baking out materials
