Hi

For my custom implementation i need to found neighbour triangles by edge for current triangle. For example triangle with vertex indices 0,1,2 is neighbour for triangle with inidcies 0,2,3 and second neighbour is 0,1,4

But UE is add duplicates vertices when importing mesh and compare just by vertex indices is not possible. What the best and fast way to find triangle neighbours?
