I'm currently looking on if it's possible to make a Vector Displacement Map, as ZBrush or Mudbox, in Houdini ? I don't know if it's possible, even with Arnold for Houdini.
I found some old topic on H10 or H11, but as I understand it, it was to read displacement map in Houdini.
Any clue ?
PS : this is that kind of result, I'm currently looking.

PS2 : I'm sorry if I made a duplicate post on that question, but the search function on the site didn't give me anything. And Google result send me on the forum's homepage =/
