poly count check

What is the best way of knowing how much poly count there is in a level.
I know that you can see it in statistics “sum tris” but it seem to be double of what I have in Maya?

Hi, maya may show a different poly count than UE. Basically you can up to triple the vertex count, cause if you have a sharp edge, then those vertices will be duplicated and everywhere where you have a seam in the UV, the vertices will be duplicated as well. So you can up to triple the vertex count.

Also, in game engines they only use tris, whereas in programs like Maya it can have quads and other polygon shapes. It all gets converted to tris in the game engine
