Syntax

namespace FaceGroupUtil
{
    void FaceGroupUtil::FindTriangleSetsByGroup
    (
        const FDynamicMesh3 & Mesh,
        TArray< TArray< int32 >> & GroupTrisOut,
        int32 IgnoreGID
    )
}

Remarks

Collect triangles by group id. Returns array of triangle lists (stored as arrays). This requires 2 passes over Mesh, but each pass is linear
