Cloth for Unity3D: Can I use a polygon and still see both sides?

Cloth for Unity3D: Can I use a polygon and still see both sides?

I'd like to create a cloth object (think of a flag, sailboat sail or parachute) in C3D to use in Unity3D and I'm wondering how to approach this. I can create a "thin" solid cloth but it looks ugly.

I'd like to be able to have a "membrane" if you will and somehow render both sides. Would I do this with some sort of double normal vectors? A custom shader in Unity? Other?.

I'd also like to animate it.

I'd intend to programmatically create the vertices/polygons/normals to get the shape I want but I'm at a bit of a loss at where to go from there.

I've seen tg_jp's wonderful Wavey plane demo BTW (http://www.cheetah3d.de/forum/showthread.php?t=664). I've imported it into Unity3D but I wasn't able to get the animation to work and it's only rendered on one side.

Thoughts?

thanks in advance,

To make polygons that are visible from both sides, simply duplicate and flip.

Just for clarification - do you mean flip normals, or turn the actual geometry around?

Funny thing; try this: http://i194.photobucket.com/albums/z163/soul-sides-com/12360Vogue-Man-I-ve-Flipped-Posters.jpg

(Sorry, couldn´t resist)

Now Frank, are you sure it is not this:

Thanks! That was one of the first things I tried (using copy+paste, flip normal) but thanks to your advice I tried again using Clone this time and it worked.

thank you so much!
