Blender Model - Front Not Showing

I have a blender model, but the front does’nt show. (Yes, it is the front, rotating the model doesnt help). Does anyone know why this might be and how to fix it?

Heres a screenshot of what i mean:

It probably has a default ZBufferState applied. Set a ZBufferState with:

ZBufferState zs = DisplaySystem.getDisplaySystem().getRenderer()




(typical values)

Thanks! It works now.

Sorry I have so many questions.  :// Makes me feel as if I ask too many. ://
