- Always model the simplest control cage possible.
- Always view your model with smoothing or render it using PxrVisualizer.
- You can even model in a live PxrVisualizer render !
- Use creases to make sharp or semi-sharp edges without adding extra edge loops.
Corners work like creases for vertices.

Column In this animation, 3 edges of a triangular face have a crease value of 5.0.
We increase the triangle's corner values from 0 to 5.0.
Note the very smooth transitions around the tightened areas.
- There are 3 type of subdivision surfaces.
- Catmull-Clark is the most flexible and popular one.
- Loop is a triangle-based subdivision surface.
- No creases or corners
- useful for cloth simulations
- Bilinear is like a catmull-clark with infinitely hard creases on all edges

Often, it is better to rely on displacement and bump mapping to add details.
