Why I Should be triangulate model?

[Fabiantronc]

Hi.

I don't know for what exactly do that, can anyone explain me the benefits of it?
and it's neccesary closed the model on Topology and conversity on O2?

Thanks in advance

Triangulate?
You use the \ or / key
- Used where curved surfaces don't look good with just squares
- Has to be used for whole of Shadow LOD. Also everything has to be "Sharp"
- Shadow LOD also has to be closed.

Right now can't think of any real reason you HAVE to use triangulate or closed.

thanks for your reply Gnat

As said, only shadow LODs need to be closed, Triangulated, and sharpened. Doesn't matter for anything else.

Triangulating will also remove non planar faces and non linear mapped faces (in your O2 menu....Structure>Check faces .... will add any faces with errors to the named selection list)

One reason, and possibly the biggest reason that any modeler will tell you is simply cuz of your model and curves.  Some curves don't need it if you make sure they don't or they're extremely high poly, but doing that is a pain in the ass and time consuming. 

However, simply clicking / for everything isn't a good idea for you model.  some areas need fine detailing and care to make sure you've used /  and \ correctly.  there's a huge difference between \ and /, i.e. the lighting, the model itself, curves reletive to it.

Simply, make sure when you do use / or \ that you use the correct one.  Don't half ass useing triangulate.

as for closing stuff, outside of shadows, if u can't see the face, doing put it in there or ur just wasting faces.
