Is it possible to show vert count in Maya the same way Unreal does?

malcolm

Just wondering if anyone has figured out how to calculate the vert count in Maya so it will match with Unreal. After importing almost any mesh into Unreal the vert count grows significantly, I'm assuming this is because of UV splits and hard edges, but I'm wonder if anyone knows how to predict this in Maya, and if any knows exactly why the vert count grows in Unreal.

In the MEL line, type "polyEvaluate -v" this will get you the vert count. Replace -v with -uv and now you get the UV count.

I made a sphere in maya then I typed these while the sphere is selected:
"polyEvaluate -v" resulted in 382
"polyEvaluate -uv" resulted in 439

Yes it's from 2008, but the 2011 python documentation doesn't include the "-" which gives errors.

Otherwise, export your model from maya, load it in 3ds max and use UberVertCount.

The UV number should be closer than the vertices number. If your hard edges are the same as your UV border edges, then, UV number in maya should match verts number in Unreal.

We tried the UV count thing, it only works for certain models, other models are wildly different in Unreal. Any other suggestions?

That covers UV splits but not hard edge splits like eltarbos mentions. It's been a long day and I'm having trouble thinking this one through fully. Also, what maya version? Looks like polyEvaluate got buffed in 2018. -<b>uvEdgePairs</b>(<b>uep</b>)&nbsp;would be handy here at least. (how do i escape this textual hell?)

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.

if you have a hard edge you should have there an uv seam otherwise you wont get a clean normalmap...

Did you ever figure out the correct way to calculate this?  I am trying to figure out the same thing.
