Objects not colliding

I was trying out the Nxogre tutorials and I managed to generate a .nxs file using flour and the problem it is not colliding with the cube.mesh which is supplied with the Nxogre media pack.

Am I generating the .nxs file wrong.


I have used the above mentioned command to generate the nxs file.
I have tried all the --types(Triangle,convex,mesh), No luck.
My object is a simple box.

Help please
