Matching Unreal's vertex count in Maya?
This thread talks about it. I would like to figure out how to calculate in Maya the number of vertices that an object will have when imported into Unreal.

In that thread, @throttlekitty says: "I think a script for this would need to get number of verts, +1 for each vertex on a hard edge that isn't a border, then +1 for each uv seam that isn't also on a hard edge or a mesh border."
I have a script that calculates the vertices on hard edges. But I don't know how to find the second part - the uv seams that aren't on hard edges or mesh borders. Anyone know?
I was thinking that this might be helpful, but I'm not sure:

lets assume its a normalmap based workflow, then you place hard edges where you have UV seams, otherwise you get shading errors.
So i guess the only info you need is the verts on UV seams?
i mean yeah you can find both and subtract them from one another, but i guess only broken meshes would have that case of hard edges where you do not have UV seams?
