How can i see my triangles from a scene / level (total or what is on screen)
Take a look at this thread: How do I see the triangles count in my scene? - UE4 AnswerHub
Consol command: stat RHI
It’s showing some weird numbers… For instance, in a scene with no objects at all it shows about 30k triangles. In a scene where it should be about 4-5 mil tris (if I just multiply mesh tris * meshses count), it shows 7-11 mil tris…
When used in the editor, it counts all triangles rendered in all open editor tabs and windows too, including the editor UI.
