  1. Color Management Rules ?

    Right ... so if I am reading this correctly ... the standard ocio naming conventions drive how Houdini interprets image types ... but currently there is no customization for studio rules. Will keep this thread alive with any information we come across.
  2. Hey guys ... we are looking into establishing an ACES pipeline, I was curious if Houdini had any sort of color management rules system similar to Maya. Here is a screen capture of the Maya implementation that applies rules to image types. We are going to start by using Arnold's .TX format to apply these rules to each image category. Thanks Mike
  3. access menu item

    that is exactly what I thought you were going to say =P ... so a wrapper seems like the best way.
  4. access menu item

    Is there no way to build the menus with python on launch .. similar to Maya usersetup.py ? I'm just getting started w menus now and was trying to avoid hardcoded xml. Thanks
  5. getting active input from a switch node ?

    better than just listing an answer !!! thanks !
  6. Can anyone tell me how to get the active input from a switch node in houdini ... I have a bunch of file nodes going into a switch and I want to grab the active nodes filepath. Thanks.
  7. I am working with VDBs for collisions ... everything looks good up until the point that i convertvdb back to polys. I am getting visible voxel bands in my mesh. Can someone tell me how to avoid this ? VDB on top ... Conversion on bottom.
  8. Smoke & Mirrors ... a NYC post house needs an artist capable of create a macro demo with a biomedical feel. Should be comfortable with Flip/SPH Fluid, Particles, Pyro as well as procedural animation and deformations. This project is self contained so working remotely is a possibility. If you are interested you may contact me directly here for more info using PM here. Thanks
  9. Need Wire Constraint Help

    of course ... thanks ... regarding debugging ... aside from the spreadsheet is there any other tool you use ? btw : I am checkout out bosnak's scene and so far i agree. =)
  10. Hi .. I am trying to follow along with a tutorial that goes over wire constraints and pins. I cant get it to work properly. If anyone has any brilliant ideas ... let me know. here is a hip ... wires_3.hip

  12. Help!My Pyro does not work

    What is not working ? are your sources generating density and heat ? Can you be a bit more specific ?
  13. I am working with POPs and I want to emitted a random number of particles every N frames ... so I am using the following in my impulse count.... if($FF % 20==1 , fit(rand($FF*5), 0, 1, 0, 10), 0 ) to emit between 0 and 10 particles every 20 frames. My question is ... how can I create a sorry of fuzzy emission frame ... instead of every 20 frames ... id like it to be ever 20 frames with a few getting emitted within a given tolerance of 20. Thanks
  14. That fixed it ... I am doing my alignment inside the popnet and the normal is staying fixed at speed of 0.
  15. Here is the wrangle code I am using to align the normals... if (@speed > 5) {@N = -@v; v@lastalign = @N; i@stopped = false; } if (@speed <= 5){ i@stopped = true; @N = @lastalign; } For some reason the normal is still getting set to 0,0,0 even though I am setting it only if the speed of the particle is above 5. It just occurred to me that maybe I should be doing this inside my popnet ?
