Question by Disaster · Dec 06, 2009 at 12:59 AM · optimization

Planes with less tris

Hi,

Why is it that Unity planes have so many tris? As far as I can see, there is no way to change this, and it sometimes seems unnecassary to have so many tris in a plane. When I just want to import a static image (for a foreground of background), I was wondering if it would make more sense to import a plane from Maya with just two tris instead?

I understand that the extra tris of Unitys planes arn't exactly going to bottleneck my game, but I'd rather not throw them around needlessly.

Any thoughts / tips would be greatly appreciated!

Thanks.

When you use GameObject->Create Other to create a plane (or a cube/sphere/capsule/cylinder), the editor is creating a GameObject for you with its built-in plane mesh attached (from unity default resources). You aren't able to change the subdivisions because this mesh is not really special in any way (aside from being built-in), and appears as an arbitrary mesh to Unity, just like any other one you might import from Maya.

As you guessed, if you want a 2 tri plane, you should import your own from Maya.

I don't know the answer to the question "why". My assumption is that the built-in plane has many vertices because a heavily faceted plane gives more usable results with vertex lighting. However, I already answered you here that yes, you should "model" your own quad, and not use Unity's planes.

Thanks for your reply. I understand both questions are very similar, sorry if I have made you repeat yourself.

I think the vertex lighting argument sounds very reasonable. I think in general, a few more or less vertices don't really matter (unless you're on the iPhone which is a whole different field). However, pixel lighting vs. vertex lighting can make quite a significant difference.
