Hi again. Just a general question about polygons in Maya.

So for I've been merrily modeling away and my polygons appear to be double sided (shaded and visible from both sides), and I've not given this any thought, but should I?

In a program like Lightwave, unless you make a polygon double sided it is one sided, and it's normals face outwards. Sometime you get flipped polygons that need to be corrected.

I know that Maya has a bunch of Normals tools so it must also be a thing to look out.

My object seems to render okay but is it important to establish the unified normals of all objects and how do I see that when they are double sided to begin with?
