Why can not see the back of custom mesh

Hi ,

I am drawing something with mesh, when I finish found that if you move camera to back of the mesh, the mesh disappear.

I tried to find something in custom mesh tutorial, it was the same; I also tried to change its MaterialDef, still can not see it from back.



Any suggestions?



Best regards.

material.getAdditionalRenderState().setfaceCullMode()
