Houdini PRT ROP

Update: new releases added for Houdini 18.0.391

Since people are still asking for it, I’m trying to keep the PRT ROP for Houdini somewhat current. You’ll always find the latest version on Github:


Installation is straight forward: just download the zip from the Releases page on the repo, then unzip the .dll file into your houdini’s profile dso folder. On Windows that folder is most likely somewhere like this: c:\Users\yourusername\Documents\houdini18.0\dso\

If the “dso” folder does not exist yet, just create it. Then drop the PRT_RopDriver.dll in there and start Houdini. You can then create a PRT_ROPDriver ROP node in the Outputs.

  1. Hi,
    I am a big fan of your PRT exporter plugin for Houdini. 🙂
    Are you going to make a new version for Houdini 17 ? It would make me and my friends very happy.
    Thank you very much.

  2. Hi Michael,
    I promised guys at work to message you :). Is there any chance you will find time to release PRT for Houdini 17.5? We all very much appreciate your exporter :).
    Thank you very much.

  3. Hi Michael,
    Will you find the time to make an update for PRT exporter for Houdini 18? Also, I feel bad to always text you and bother you with it so if you point me to something where I can find how to make it my self or how to update my self. I will gladly take the relay after you and share it with others as well. 🙂 Thank you.

  4. Hello, everybody,
    first of all thank you very much for the plug-in PRT ROP.
    According to your description I have
    created a dso folder in the directory c:\Users\yourusername\Documents\houdini18.0 and put the plugin dll there.
    Unfortunately I cannot call this node in Houdini (Indy version), I see many ROP nodes but not the PRT-ROP node, am I doing something wrong?
    I am looking forward to a short feedback – Thank you very much!

    1. Are you in the ROP context? Because that’s the only place it will show up. See screenshot:

      This is the location where I put the file:

    1. You write out prt sequences just like image sequences. PRTs are single frame point clouds, there’s no animation in there.

  5. Thanks for your feedback. How can I write a sequence of e.g. 1-100 frames as a sequence out of Houdini or read it back into Krakatoa and render it as a sequence – or is that not possible or is there a work around for it?

  6. Hi Michael. Do you have some spare time, please? With the latest update of Houdini 18.0.391 Houdini shuts down when you try to put PRT node down. We have tried to compile it but with no success. Can you help us with it? Thank you
