quad vs plane as terrain

Questions & Answers
1

i’m going to use rectangular-shaped terrain in my project, but i’m not going to use unity’s terrain 'cause my terrain will be 500x500 units and for unity’s terrain i would have to use multiple terrains for this.

terrain would be simply plain, without hills.

so i can’t decide what is better for performance: 1 quad or 1 plane with lots of triangles. the camera will see only a small part of terrain at a time, so i’m wondering, what will render better - plane or quad?

A quad has four vertices and two triangles.
A plane is like a 10x10 grid of quads joined into a single mesh.

Unless you’re going to deform the interior vertices or assign UVs to them for texture-mapping purposes, I can’t think of any reason why you’d use a plane over a quad.
