  1. ok so some progress with PDG following Ari's tutorial, https://vimeo.com/323291527 but getting ImageMagick running properly on OSX is a total PITA! After installing, adding proper pathing to houdini.env it runs but no support .exr by default. Get the following error So thinking I need to install OpenExr I do so and get openexr 2.3.0 is already installed and up-to-date Any ImageMagick experts able to suggest a solution? Guessing this will be easier on my Ubuntu box....
  2. Simply trying to cook a ROP Mantra node inside a TOPNet and repeatedly get the following error when that node definitely exists! What am I missing?
  3. Houdini REST and Three.js

    Is the version for Unity available?
  4. Randomly choose between 4 options

    Thanks. Is there any way in vex to incorporate method calls directly with your solution, or would I still need to use an if, else once I get my @choose value?
  5. Awesome. Please share more. Would be great if you could do a tutorial
  6. What's the most efficient way in vex to choose between 4 different options? Right now I am simply using rand and a series of if statements to check the resulting value. Is there a better way?
  7. Going thru a tutorial on L-Systems and OMG, just seems like an overly complicated system for creating results that aren't necessarily that organic looking. Does anyone actually use L-systems in the real world?
  8. I want to change the name of an existing parameter for a single instance of a Turbulent Noise VOP. Using Edit Parameter Interface it seems I can change the name of any parameter but when I hit Apply and Accept the changes don't happen.
  9. Hi Am I correct in assuming the default scene lighting (without any lights or applied materials) in H17+ is different than in earlier versions? What do I need to do in order to match the lighting of earlier versions?
  10. Any python wizards? Confused about the various python installs both in OSX and Linux. When I do a python -V in terminal OSX I see Python 2.7.16. Yet in the Houdini Python shell I see Python 2.7.15 (default, Dec 12 2018, 14:09:37) > Where exactly is the location for the default Python install for Houdini in both OSX and Linux? And how can I change this?
  11. Disco Dingo

    Any Ubuntu users? Wondering if I should upgrade to 19.04 which comes with the new Linux 5.0 kernel. Supposed to have improved support for nvidia GPU's but came across at least one thread on reddit warning about upgrading. https://www.reddit.com/r/linux_gaming/comments/ax3msr/beware_of_kernel_50_nvidia/
  12. Houdini not exporting geometry to FBX?

    @Alain2131, ditto, thanks for sharing this. Seems to solve at least one issue with bringing in even static FBX files to Unity....keeping geometry separate and accessible!
  13. FBX workflow to Unity

    Having problems in a basic Houdini to Unity FBX workflow. I am using the material shop path assignment method where I simply create a SurfaceShader materal inside a Shopnet in Houdini and apply it to a Primitive group before exporting using FilmboxFBX. When I bring it into Unity I cannot seem to figure out how to access and or apply materials. Are there any specific FBX export import settings I should be using? If I use separate SOPs for my geometry in Houdini, shouldn't these separate geos be viewable in my FBX after I bring it into Unity? What would be super helpful is a simple Houdini file, say just a cube and sphere with separate materials, and then the corresponding Unity file after imported as FBX. Any help appreciated...really want to get this to work.
  14. SDF's, are they all equal?

    Thanks Henry. So not the same.
  15. One thing that seems to be glossed over in many tutorials is the relationship between native, non-native VDB volumes and SDFs. So an SDF can be created both ways, using native volumes via ISO Offset and aslo via VDB's using VDB from polygon. But can anyone tell me what the difference is between these 2 SDFs? ( created using ISOOffset and a SDF created using VDBfromPolygons)
