Thanks you very much for the fast answer 

Thanks for the explanation, helps a lot.
And finally, thanks for the solution of my problem, it's "working" (rendering the back) now

Keep up the good work

Hi,

First of all i would like to thank jPCT team for their great work.
I'm new to jPCT and 3d modeling for android so please don't blame me for my incompetence.

I have a problem with some of my objects
Mainly what i do is loading a .obj within the demo application (for Android). They are well display except that when I rotate them, they become transparent when i'm watching the "back" of the object
(see : https://www.youtube.com/watch?v=5TSbpx_eM2k)

Thanks in advance for the help
