Double-sided material

Thought I would start to learn the new art workflow since T3D is on the door step. I have exported a model to COLLADA and once importing using the Collada Test, I do not see the double-sided material on the model.

I have checked the COLLADA file to ensure the material information has been transferred over.

model.DAE

<double_sided>1</double_sided>

Also, the material file generated by Torque also backs this up
material.cs

doubleSided = true;
