Have You tried using a valid material for the plane instead of null?

plane = new Plane(null, 50, 50, 6, 6);

Cheers,

daniel.

I tried applying other materials but the plane is displayed only for once and then just disappears.

Plane seems to be working fine with Camera3D. Other primitives are working fine with FLARCamera3D. Its just the plane that's not working with FLARCamera3D.
