Syntax

void DuplicateTriangles
(
    const TArray< int > & Triangles,
    FMeshIndexMappings & IndexMaps,
    FDynamicMeshEditResult & ResultOut
)

Remarks

Duplicate triangles of a mesh. This duplicates the current groups and also any attributes existing on the triangles. Make a copy of provided triangles, with new vertices. You provide IndexMaps because you know if you are doing a small subset or a full-mesh-copy.

Parameters

Parameter	Description
Triangles	the triangles to duplicate
IndexMaps	returned mappings from old to new triangles/vertices/etc (you may initialize to optimize memory usage, etc)
ResultOut	lists of newly created triangles/vertices/etc
