I am still having a problem. The face is quads and the shirt is tris.
However in 3ds max. The face becomes tris and the shirt is quads. I have no idea how to control this?

Thanks, it's working now! guess i activated InstaLOD before, which may have caused triangulation.

If the mesh is quad (which you may verify by switching to Wireframe modes), then it does export as quad.
At least that is what I am always getting exporting out of CC3 and importing to Blender:

It should be quads according to this announcement - however, the exported mesh is triangle:

• New topology is 100% quad mesh, ready for subdivisioning and mesh editing.
• Quad wireframe view for expedited surface inspection.
• Enhanced mesh and high-res texture details for the hands and feet.
• Optimized skin-weighting for naturalistic bending of the joints. 

Currently testing the CC FBX export function (rigged skinned skeleton). When exported, the mesh is triangulated. Is there a way to get a quad mesh instead?
