Correct workflow for this Cylinder.

Hayden Zammit

Pretty sure this will seem a stupid, rudimentary question to a lot of you guys, but I gotta ask. With this pic I've got two cylinders. With one I merged all the verts and the other I didn't and kept it 4 sided.

Now, is it okay to have them all merged like that? It saves me wasted geometry but it does make it all tris for that object. I've read some places saying that you can have tris and quads, others saying that it should be just quads, etc.

I'm using the Unreal engine for this project, so I know it will all get turned to tris anyway.

So, now real advantage to either?

with flat cinders I hear option B can be better performance wise, depending on the engine.

The image is from this article, might help you.

Be aware though, since that article was written, graphics cards (and consoles) have gotten much more powerful, to the point where these kinds of optimizations don't make enough of a difference to justify the time it takes to do them.

If you're doing something for simpler hardware, like an iPhone, it might still make sense though.
