The Subdivision modifier implements Pixar's subdivision modes to subdivide low-polygonal objects into smooth surfaces. The main advantage of using this modifier is that you can keep your MXS scenes light, and thus they will open faster, take up less space on your harddrive and also transfer faster over your network when doing network rendering.

Level

Indicates the number of iterative subdivisions of the object. 

Type

Allows you to choose between Loop and Catmull-Clark subdivision algorithms. 

UV Interpolation 

Allows you to choose the interpolation of the UV coordinates for the new geometry, choosing from: 

• None: doesn't perform UV interpolation 
• Edges: interpolates the UV coordinates from the UV coordinates of the nearest edges 
• Edges and Corners: interpolates the UV coordinates taking the UV coordinates of both the nearest edges and corners 
• Sharp: 
  
  

Edge Crease 

When set to 0, the polygon is divided evenly at the middle of its length. A higher value approximates the new edge to the original edge, concentrating the subdivision near the edge. This setting is useful to preserve the original shape.
