double sided textures on planes


I’m trying to texture some leaves, and on 1 texture it is double-sided, but on the other two it isn’t… any ideas?

Top image shows the top of the planes, and bottom image shows the bottom.

Let me know if you need more information!



Ok, I’ve narrowed it down to a normal map going in to the diffuse which is making it go quirky… can’t see a difference between the good and bad ones though…
