Is a mesh with quads that share vertices better performance wise than quads that don’t share vertices?
Not sure if I saying it the right way so I guess what im asking is if a mesh with the quads “connected” better than a mesh with quads that are not connected?
Hi Spool,
In general the fewer vertices you have the best it is. FYI Unity operate by default on triangle list and optimize meshes for vertex cache. Duplicating the vertices is thus something no recommended unless you want to have different smoothing group (ie normals) for example.
Hope it helps
