So I’ve been importing some models in to Unreal Engine 4. In my modelling application the vertex count stands at 1,498 and the polygon count at 2,442 however when I import the model in to Unreal Engine the vertex count doubles to 4,225, the polygon count remains the same.
This leads me to believe that Unreal Engine duplicates all the vertices that two or more polygons share. I read on the internet that this is called vertex indexing and that when your graphics card renders the model it will only render 1,498 vertices as the modelling application shows and that I shouldn’t worry about it but focus on the polygon count only.
Is this true? Am I importing the model wrong? Whats going on?
Thank you in advance.
