[SOLVED] Need hint for showing material color inside cave bodies


I created a sphere, I attacched a MaterialState (green) to its RenderState. Now when I move the camera view far from the sphere I can see it green, but when I enter inside the body of the sphere all it's grey. What's the hint?

Tnx to the great jME Scene Graph Viewer I noticed the property FrontAndBack

So for other newbye like me having this problem, voil
