Good afternoon, tell me why the editor creates new vertices in the model when importing. I tried to import from different editors (Blender, Cinema 4d) For example, in Blender a sphere has 482 vertices, when imported into UE5 the same sphere has 1984 vertices, this is without LOD and all vertices are stitched
It’s probably because geo in the engine relies on triangles and not quads 
I tried it in different ways. With both quads and tris
UV seams and hard edges increases vertex counts in game engines but not within 3d modeling programs. It’s not uncommon for vert counts to increase dramatically.
It’s strange, but it really works. With different scans, there are different numbers of vertices. Tell me, is this a normal parameter, do these new vertices not affect the optimization? do you need to get rid of them?
