  5. Path for Houdini self learn

    Give yourself a task and then try and complete it - I find this a good way to learn. e.g. find an effect someone else has done and then try and replicate it yourself. The first thing I did was to make a procedural fence asset so that taught me to use some basic math, introduced the copySOP with stamping, switches, rays and some simple modeliing techniques.

  9. L-System Pivot

    Hello, Does anyone know a way to get the pivot point of each prim from an L-System? I'd like to use this for animating bends and rotations but I'm not sure how I would go about it. Logically I need to find the nearest point on the previous gen to the 0 point of each primitive but it must also take into account the transforms of the previous gens too. I looked in to matt estela's rotation matrices but this doesn't account for the previous gen's transforms. Any help greatly appreciated. http://www.tokeru.com/cgwiki/index.php?title=HoudiniVex#Rotate_prims_around_an_edge.2C_alternate_version
  10. Capture to disk and Mplay

    Bump. Has any progress been made on this? I realise you can write to disk using viewwrite -f 1 10 Build.panetab1.world.persp1 '$F.jpg' and write to mplay using viewwrite -f 1 10 Build.panetab1.world.persp1 ip but I'd really like a way to script writing images to disk from mplay. Even knowing if/where mplay temp images are located would be a start.
  11. 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?
  12. 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.

  14. Python - Houdini Engine

    Anyone scripted anything for Houdini Engine in Maya? Just want to be able to import an HDA. Any pointers appreciated.
  15. 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
