Modelling Question

Benton · May 2012

Hey everyone,

Quick modelling question,

I am making a building with four walls. It is one mesh, but the four walls are not connected. It does not raise the triangle count, but it does raise the vertices count. Is that a bad thing? Should I subdivide the walls and connect the vertices?

it really makes next to no difference, yes the vert count is higher when the walls aren't sharing verts on the edges, but it;s not like 6 extra verts or what ever it is will mnake a performance difference.

but will a lot more verts cause performance issues?

ya but what kinda numbers are you talking about? What kinda hardware is it running on?

everything as far as performance goes is relative, and the vert/tricount isn't the only consideration.

like the case your talking about, your saving only handful of verts, so there will be no noticeable difference.

If the walls are 90' angles, chances are you're going to have them in different smoothing groups if they were connected? I don't think there's really going to be any different in verts (unless you subdivide and then connect them, which sounds like adding more?)

Yeah if I loop cut then I add more, if I use n-gons they will be converted to tris which will create even more verts.

I am just wondering if verts do cause performance issues on mobile. I don't see how they could, I mean it is not rendered. Even if I had 100 extra verts would it cause issues on mobile?

That doesn't sound right.

n-gon to tri = verts being created...

...how / where?

A polygon made of 7 verts shouldn't suddenly have 8 or 9 just through triangulation.

Ahh your right, my bad.
