There is a paper on how to reverse Catmull-Clark subdivision:

AFAIK there is no implementation of this in Houdini, so you will have to implement it yourself if you want this feature or send an RFE to SESI.

I would love this, its a notable omission. Last I checked its available in zbrush, maya, c4d, max, blender. Even nomad on ios/android has it!

Please send an RFE to sidefx, that helps it get noticed...

The addition above in the comment works. I didn’t test it on a complex model, but it worked perfectly on a simple pig’s head. The author is a genius.
