Is there anywhere mentioned in the Doc the correlation between the index of the faces before a detach and the index of the faces to the detached object afterwards?
Its way to expensive to try to manually remap a hipoly mesh detached from an even higher poly mesh by comparing positions. even using using the SDK.
Best regards,

can’t say I have a direct answer, but perhaps you can store the face numbers into the faces using whatever data channel is available for faces, and then read that back out after the detach? That should save on compares, at least, but takes an initial run pre-detach to store the data.
You could in essence “redraw” the mesh from scratch by creating the verts and polys and then create your own association between indexes.
