So I'm trying to make a plane mesh out of triangles using subdivision. It "works" fine, however, I want it to look like the left, but when I go to use the mesh I made, it turns out like on the right. They both use the same shader/material in Unity, so I feel it has to be the mesh that is causing this issue. I have no idea on terminology, so I apologize.
Edit: Here's what the planes look like flat. As you can see, the one I made (right) has obvious triangles still when flat, however the triangles are almost unnoticeable on the left.
