Double sided polygons?

Hey, folks,

Just a quickie - does anyone know if there’s a way to render double sided polygons on iPhone? This would make things a lot easier (and I suspect, easier on the GPU) than “doubling up” the poly’s to make both sides of a plane visible…

Anyone?

You just need a shader for 2sided texturing.
The nature shader for vegetation for example is 2sided and works fine with iphone.

You can add a “cull off” row in your shader and remove the back polygon
