  1. Urgent: How to get Very Soft Splashes

    How about just doing a sim as you normally would be then using the VDB tools to sculpt it / smooth it into a less defined shape?
  2. Need advice from Houdini users.

    Yeah - houdini is becoming more and more artist friendly so knowing the maths is useful but not absolutely necessary. Anything you don't know can always be googled Python is not necessary at all but again, any additional skill is useful. If I were to invest in my future from scratch I would do it with SideFX not Autodesk for sure. They are considerably more customer-centric, they listen to their user-base and you can get their software free to learn with the PLE version. There's tonnes of learning content out there with Peter Quint, entagma, Rohan Dalvi, Go Procedural, sidefx.com and here on odForce. The community is really helpful and can always get you out of a pickle. I'm an XSI convert but I'm glad autodesk canned it as it gave me the push towards this sensational piece of software.
  3. Python - Houdini Engine

    This was quite handy https://www.sidefx.com/forum/topic/39115/
  4. Python - Houdini Engine

    Anyone scripted anything for Houdini Engine in Maya? Just want to be able to import an HDA. Any pointers appreciated.
  5. Hello there, I'm mucking about with houdini engine in maya and used the bog-standard file hda to get particles in there and it works. So to add some level of control into maya I thought I would add a delete SOP after the file SOP and have this controlled by a slider on the top level of the hda so that within maya you can dial out some particles if needs be. This works as you would expect in houdini but has no effect in Maya. So my question is this. Is this functionality possible or does it fail due to the limitations of nParticles? If it's not the latter then, anyone know what I'm doing wrong? Cheers
  6. Python - Parameters 'Type'

    Scratch that expressionLanguage()
  7. Python - Parameters 'Type'

    Thanks chaps - so added to this, is there a way to determine which language is used in the expression e.g. Python/Hscript or is it simply a case of interrogating the code to determine what it is?
  8. Rendering Pyro

    Thanks chaps, I'll take a look at this. I haven't had a chance to go any further with looking in to this problem but one difference is that one camera is alembic imported and the other is created natively. It's a non-issue at the moment as my shot cams will be alembic imported but I was curious.
  9. Rendering Pyro

    I'm clearly being an idiot here. Can someone explain to me why if I render a pyro sim from two different cameras it looks totally different - even the alpha is different? One is wide and far the other is close up. One directional light, mantra. Is this a scattering issue within the shader? I'm using the stock pyro material but I've removed the flame colour bits and thrown in a heat>fit>ramp into the emitcolor instead.
  10. I wasn't totally sure where to post this. Has anyone come across the houdinifx.exe, houdini.exe etc staying within the processes list on Windows after Houdini has been quit? It appears to be only happening on this machine, I've not had a problem on others. Houdini 15.0.416 Windows 7 I've currently got a batch script to kill all instances of it - but it's not ideal when some processes are hogging many Gigs of Memory.....
  11. Exporting Houdini Particles to Maya

    That's the point. You cant import Houdini particles into Maya with Alembic. It seems that every other DCC on the planet has this ability but not Maya....... Even dead software like XSI can handle this. Autodesk are a shambles.
  12. Exporting Houdini Particles to Maya

    Is this really still an issue? https://forums.autodesk.com/t5/maya-forum/alambic-importing-partical-erro-error-line-1-particleshape1/td-p/7040953
  13. Python - Parameters 'Type'

    Ayup! How do you evaluate a parameter to determine it's contents 'type' - e.g. expression/string - 'type' method is currently crossed out in the docs http://www.sidefx.com/docs/houdini/hom/hou/Parm import hou sel = hou.selectedNodes() for i in range(len(sel)): for p in range(0, len(sel[0].parms())): sel[1].parms()[p].set(sel[0].parms()[p].eval()) print str(sel[0]) + ' = ' + str(sel[0].parms()[p].eval()) print str(sel[1]) + ' = ' + str(sel[1].parms()[p].eval())
  14. Python - Maximise Viewport

    thanks - this was implemented in h16, right? I'm on 15 right now - so not currently an option.
  15. Python - Maximise Viewport

    Anyone know how/if it's possible to maximise the viewport in python? cheers
