Problem with Blender exporter

Hi guys,
I am starting development on a game using libgdx, just started modeling in Blender and i ran into an issue. I made the model, unwrapped it, applied material and texture. Everything works fine in Blender but when i export is either as .fbx or .obj and try to render it in libgdx, nothing displays. The problem is Blender does not export my UV map and sets the material opacity to 0. I converted the fbx to g3dj for libgdx use, and when i open it in a text editor, the opacity is 0 and the UV map is blank

Blender Render:

After setting opacity to 1 in g3dj:

I have tried everything. Any help would be greatly appreciated!

have you tried exporting to .obj using blender render materials instead of cycles materials

Thanks for the tip, Richard, I managed to make it work using blender materials. Anyone else having problems with cycles materials? They work fine in blender but won t export properly.
