  1. Great speech from Mark also. Totally cool.
  2. It's actually quite demonstrative attitude towards them...
  3. Render to pointcloud?

    Check out pcwrite function help for working example of such shader: http://www.sidefx.com/docs/houdini/vex/functions/pcwrite.html hth, skk.
  4. Houdini and hython/hbatch/engine is simple: hou.isUIAvailable() // spots the difference For python in Mantra filtering, check if you can import mantra module, and handle exception properly is_this_mantra_filter = False try: import mantra is_this_mantra_filter = True except: pass For python running inside HDA instanced by Mantra afaik it is less obvious. I can deduce it from a details like content of sys.argv. From what I see in Mantra case it's empty: import sys if not sys.argv[0]: # this seems to be Engine running inside Mantra pass highly unreliable. hth, skk.
  5. Create HDA using python

    hou.Node.createDigitalAsset() + 10 other hou.Node's methods dealing with hda.
  6. Yes. Use RAT texture. Mantra doesn't use tilling nor mipmapping in EXR format (even if file itself is tiled and mipmapped).
  7. Ubuntu will work minus graphic card drivers (better to switch to default video driver at old machine). Windows probably won't (at least it never was with Win7).
  8. Afaik HDK doesn't expose any headers for Mantra's camera, but you might take a look into lens shaders, like ASAD lens shader (v_asadlens shop) to control camera projection.
  9. kwargs in python shell ?

    print hou.node("/obj/myHDA").hdaModule().kwargs
  10. Is OpenCL 2.0 Faster than HFS OpenCL?

    You can always confront your imagination with reality measuring Houdini's performance in both cases. I wouldn't be surprised if lso OCL 1.2 code could run faster on OCL 2.0 driver. Aside of language's changes, new versions usually evolves compilation for better vectorization (I also imagine that dynamic parallelism might be used for work stealing).
  11. Maybe they have been bought?
  12. On a single computer, right? I don't see why not. You can always open multiply session of Houdini on a single computer without consuming license. Moreover, if you start hbatch on a computer used already by Houdini, it will not consume another license too. Shorty speaking Houdini will always consume a single license on a single node what ever number of processes are running on it given previously accounted license is sufficient to run new process (HoudiniFX + Houdini Core + hbatch running at the same time will consume single license, while hbatch + Houdini Core + Houdini FX, will except three distinct licenses...).
  13. Because it's just right*. * - written on a glorious MacBook Pro (13-inch, 2016, Two Thunderbolt 3 ports)
  14. Rendering slow

    CPU usage is low, probably because rendering takes a small part of the time, more is export geometry and disk operation. Go with Redshift or OpenGL render.
  15. Command Houdini on Phyton

    Yes, Houdini has an excellent (best in industry imho) support for Python scripting. Houdini Python module can be imported to regular Python session, or used inside Hython, which is like regular Python interpreter with builtin Houdini module. With Python you can do everything Houdini can offer (some omissions can be found but don't relate to anything important). Some references for you: Opening and inspecting scene: http://www.sidefx.com/docs/houdini/hom/cb/hipfile Accessing hou module from regular Python: http://www.sidefx.com/docs/houdini/hom/commandline General intro: http://www.sidefx.com/docs/houdini/hom/intro Full API docs: http://www.sidefx.com/docs/houdini/hom/hou/_index
