(Array[MeshDisplacementMap]): [Read-Write]displacement_uv_channel
(int32): [Read-Write] UV channel used to sample displacement mapsenabled
(bool): [Read-Write] If true, Nanite data will be generated.fallback_percent_triangles
(float): [Read-Write] Percentage of triangles to keep from source mesh for fallback. 1.0 = no reduction, 0.0 = no triangles.fallback_relative_error
(float): [Read-Write] Reduce until at least this amount of error is reached relative to size of the meshkeep_percent_triangles
(float): [Read-Write] Percentage of triangles to keep from source mesh. 1.0 = no reduction, 0.0 = no triangles.normal_precision
(int32): [Read-Write] Normal Precision in bits. -1 is auto.position_precision
(int32): [Read-Write] Position Precision. Step size is 2^(-PositionPrecision) cm. MIN_int32 is auto.preserve_area
(bool): [Read-Write] Whether to try and maintain the same surface area at all distances. Useful for foliage that thins out otherwise.target_minimum_residency_in_kb
(uint32): [Read-Write] How much of the resource should always be resident (In KB). Approximate due to paging. 0: Minimum size (single page). MAX_uint32: Entire mesh.trim_relative_error
(float): [Read-Write] Reduce until at least this amount of error is reached relative to size of the mesh
