By default Maya displays both sides of a polygon in the viewport, but when the file is imported into Unity only the front is rendered. I’m trying to make low poly trees and foliage and I need both sides to render in the Unity engine. I’ve looked through the documentation and did forum searches and nothing is coming up. I’m afraid I’m not using the right seach terms. Has anyone else run into this issue, and hopefully found how to fix it?
It’s all about culling. Check out this thread to learn more…
All you need is to use a shader that dousn’t have culling such as http://unify.bluegillweb.com/scriptwiki/index.php/VegetationVertexLit

However that shader will break if the front side of any of your leaf polys is facing away from the lightsource. If you don’t mind not having lighting on the leaves the only real way you can do this is with this shader:
