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:

https://github.com/flipswitchingmonkey/houdini_PRTROP/releases

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:
      C:\Users\myuser\Documents\houdini18.0\dso\PRT_RopDriver.dll

    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

  7. Hello Michael, I was able to use the prt rop to houdini 18 build 416. Since I geupgreated to houdini 18 build 499 it has unfortunately not worked and houdini crashes. Could you please recreate the prt rop for build 499. I would be happy about a new version.

  8. Hi Michael. Thank you for your great work. I can well understand that such projects do a lot of work. That is why I would like to know how I can build the prt rop for specific houdini build myself.

  9. Hi Michael,
    I am trying to be a big boy and compile the PRT for Houdini version 499 by my self. I follow the notes you left on GitHub but I am getting “ERROR: Could not find Windows Kits installation directory.” I tried my best but nothing :). Do you know what I need to do to get through it? Thank you.

    1. Have you installed the Windows SDKs? I can’t compile right now because I’m not currently using Houdini.

      1. I installed Microsoft Visual Studio, buildtools and set the env/var to MSVCDir. This is completely out of my field even I did 3 weeks python course :DD. I will look further. Thanks for the tip.

        1. Have you checked that the path in the compile.bat: hcustom -I “C:\Program Files(x86)\Microsoft SDKs\Windows\v10.0A\Include” is actually where your SDK is located? You may need to adjust that.

          1. omg omg. I am up to something. First I noticed the PRT_RopDriver.o is not on C: but in the master folder. Then I opened up the command line as an administrator. Disabled blocking from antivirus. I have PRT node in OUTland in Houdini. I will try to export some and use it in 3ds max but this is looking veeery promising. Thank you Michael
