Objs And Shaders Exporting

Hi Folks

Looking to pick someones brains!!!

Me and a friend are experimenting with the jMonkey game engine, he's a coder
and im a 3d artist with a (only 1 year) games background.

I have a model that i am exporting to test the collision, but i cant figure out how to export the textures...

I export the model and all the UV info is correct, but the shaders wont come up,

  1. How do i export the shaders? To work in maya firstly and to work in the jmonkey engine secondly?

Any help would be greatly appreciated!
Mike
