Sops in Lops

We've written out usd files from sops, and done some native lops things. But cmon. You can't be Houdini smug unless you're directly moving stuff between contexts.

Sop Create and sop import

A sop create is a subnet. Inside is sops, whatever you create in the subnet will be live translated to usd when you jump back into the lops context. Eg:

  1. Create a sop create, dive inside
  2. Create a box
  3. Jump up to lops again, there you go, a box in usd.

You've already used this in fact, the lops pig, lops rubber toy, even lops grid are all just hda's that are a sop create with some vanilla houdini sops inside.

You can also do create geo in /obj/geo land, and pull it into lops with a sop import. It works pretty much as you'd expect:

  1. Jump over to /obj, create a pig, name the geo container 'pig'
  2. Jump back to /stage
  3. Create a sop import
  4. Point it to /obj/pig
  5. Hooray, a pig in lops!
