unreal.RuntimeMesh
¶
- class unreal.RuntimeMesh(outer=None, name='None')¶
Bases:
unreal.StaticMesh
Class deriving from UStaticMesh to allow the cooking of collision meshes at runtime To do so, bAllowCPUAccess must be true AND the metod GetWorld() must return a valid world
C++ Source:
Plugin: DatasmithRuntime
Module: DatasmithRuntime
File: DatasmithRuntimeUtils.h
Editor Properties: (see get_editor_property/set_editor_property)
allow_cpu_access
(bool): [Read-Write] If true, will keep geometry data CPU-accessible in cooked builds, rather than uploading to GPU memory and releasing it from CPU memory. This is required if you wish to access StaticMesh geometry data on the CPU at runtime in cooked builds (e.g. to convert StaticMesh to ProceduralMeshComponent)asset_import_data
(AssetImportData): [Read-Write] Importing data and options used for this meshasset_user_data
(Array(AssetUserData)): [Read-Write] Array of user data stored with the assetbody_setup
(BodySetup): [Read-Write] Body Setupcomplex_collision_mesh
(StaticMesh): [Read-Write] Complex Collision Meshcustomized_collision
(bool): [Read-Write] If the user has modified collision in any way or has custom collision imported. Used for determining if to auto generate collision on importdistance_field_self_shadow_bias
(float): [Read-Write] Useful for reducing self shadowing from distance field methods when using world position offset to animate the mesh’s vertices.generate_mesh_distance_field
(bool): [Read-Write] Whether to generate a distance field for this mesh, which can be used by DistanceField Indirect Shadows. This is ignored if the project’s ‘Generate Mesh Distance Fields’ setting is enabled.global_force_mip_levels_to_be_resident
(bool): [Read-Write] Global and serialized version of ForceMiplevelsToBeResident.has_navigation_data
(bool): [Read-Write] If true, mesh will have NavCollision property with additional data for navmesh generation and usage.Set to false for distant meshes (always outside navigation bounds) to save memory on collision data.
light_map_coordinate_index
(int32): [Read-Write] The light map coordinate indexlight_map_resolution
(int32): [Read-Write] The light map resolutionlod_for_collision
(int32): [Read-Write] Specifies which mesh LOD to use for complex (per-poly) collision. Sometimes it can be desirable to use a lower poly representation for collision to reduce memory usage, improve performance and behaviour. Collision representation does not change based on distance to camera.lod_for_occluder_mesh
(int32): [Read-Write] Specifies which mesh LOD to use as occluder geometry for software occlusion Set to -1 to not use this mesh as occluderlod_group
(Name): [Read-Write] The LOD group to which this mesh belongs.lpv_bias_multiplier
(float): [Read-Write] Bias multiplier for Light Propagation Volume lightingnav_collision
(NavCollisionBase): [Read-Only] Nav Collisionnegative_bounds_extension
(Vector): [Read-Write] Negative Bounds Extensionnever_stream
(bool): [Read-Write] Never Streamnum_cinematic_mip_levels
(int32): [Read-Write] Number of mip-levels to use for cinematic quality.positive_bounds_extension
(Vector): [Read-Write] Positive Bounds Extensionstatic_materials
(Array(StaticMaterial)): [Read-Write] Static Materialssupport_gpu_uniformly_distributed_sampling
(bool): [Read-Write] If true, a GPU buffer containing required data for uniform mesh surface sampling will be created at load time. It is created from the cpu data so bSupportUniformlyDistributedSampling is also required to be true.support_physical_material_masks
(bool): [Read-Write] If true, complex collision data will store UVs and face remap table for use when performing PhysicalMaterialMask lookups in cooked builds. Note the increased memory cost for this functionality.support_ray_tracing
(bool): [Read-Write] If true, a ray tracing acceleration structure will be built for this mesh and it may be used in ray tracing effectssupport_uniformly_distributed_sampling
(bool): [Read-Write] Mesh supports uniformly distributed sampling in constant time. Memory cost is 8 bytes per triangle. Example usage is uniform spawning of particles.thumbnail_info
(ThumbnailInfo): [Read-Only] Information for thumbnail rendering
