Quickie: Exporting Geo From Houdini

houc4d_001

It just occured to me that in the following tutorials I’ve omitted one thing which is kinda important: How to get your creations out of Houdini and into another program. The easiest way that works in any version of Houdini is the right-click/save geo technique. In Houdini Apprentice you won’t be able to export geo sequences though – just single meshes. The technique goes something like this:

exportgeo_001
Right click on the node whose geo you’d like to export and select /save/geometry

exportgeo_002
Click on that funky icon to select where to savce your geo

exportgeo_003
Type in the name you like. Add a file suffix. Houdini will automatically export to the given format depending on that suffix. For alembic use .abc, for an OBJ use .obj

exportgeo_004
Click on “Accept” to export your geo. You can now import that file into any other software you like.

  1. Hey guys, congrats on this awesome initiative. The site looks great!

    Quick question related to this, I’m having trouble exporting Houdini dynamic sims to Alembic sequences… tried various ways (like the one on this page) but always end up with an empty file. Any ideas or tips? Thanks a lot.

  2. Moritz says

    Which version of Houdini do you use? To my knowledge Alembic export does not work in Apprentice. You’d need at least the Indie version for that.

    Thanks Moritz, yes I’m using Apprentice – will upgrade to Indie soon and give it a try.

    Great stuff guys, this is what i’m looking for. I’m at the beginning of learning Houdini, so i’m waiting for more Houdini related videos.

  5. Loving the tutorials guys. Quick question if you know, is it possible to export multiple meshes via alembic that will then load into c4d as multiple meshes? I’ve seem alembic caches come in as multiple meshes from maya. But houdini alembic always seems to be a single mesh.

    Have you got this working?

        Hi Moritz,

        Is it possible to do this partitioning when exporting with a ROP FBX Output node instead of Alembic?

        When I export via FBX all of my groups are collapsed in to one FBX object.

        Thanks,
        Paul

          Hi Paul,

          sorry, but I can’t answer this as I’ve been mostly using Alembic and never worked with fbx.

          Maybe Manu or the guys on odforce have more experience and can help…

          Cheers,
          mo

      Yes. Export as Alembic (.abc) That should include splines. Cheers, Moritz

  6. THANKS for the tip. I’m getting into Houdini in order to mix it up with Blender; I’m creating a feature animation and need some destroyed walls, etc, brought into Blender. Thanks!

    Hello there. Was wondering if I can do the opposite of the first question here. I have a RBD sim that ends up in C4D in thousands of pieces. Is there a way to export them as one single mesh?
    Thanks!

  8. stephane soubiran says

    I have an RBD, but in export ABC, i would like several piece object like “piece0”, “piece1”, with different numbers. For the moment, with this solution :
    ((Set a name for each individual object and then in the Alembic Output ROP select “Partition Mode: Use Attribute Value” and set “name” as attribute.))

    => i only have the SAME name for all the object in the output abc !

  9. Lars Korb says

    Awesome:) Thanks Moritz!
    Just when I needed you most!

    Hi,
    I’m husing houdini 16.5.405 (apprentice version) and when I save the geometry as an obj. The save is not working it is telling me:
    Save Failed: No such file or directory.
    I did write the name of the geo and chose the path.
    I just started houdini which means I am an absolute beginner.
    I would be gratefull If you could help because I on a school project and I’m stock..
    Thanks a lot.
    Sam

    Hi Moritz,

    Thank you for this. I didn’t know this shortcut 🙂

    Would you happen to know how you can export one OBJ with multiple meshes? I’ve tried the Connectivity + Partition sop (Object_$CLASS) deal but it’s not recognized as separate when I import in other programs. Still comes in as one big mesh.

    Thanks,
    Johnny
