Good question. The models have all been designed to render as 
subdivision surface models. The option for this is found on the Render 
tab of each object. The object nodes can be found inside the digital 
asset subnetworks. By setting the "Geometry" parameter to "Polygons as 
Subdivision Surfaces" the low resolution model is subdivided by the 
renderer at a micropolygon level. This means that you don't have to 
tesselate the model or worry about breaking it down because it will be 
smooth no matter how close you get to it.

This is better than using a subdivide SOP which just tesselates the 
model into smaller polygons. Often I will use a subdivide SOP to preview 
the subdivide then set the render flag on the low res geometry and use 
the object level setting to get the best quality results.
