  1. Deleting Points from a Primitive Wrangle

    Maybe this image will help ... I think I need to iterate over each primitive and then get the min and max value of a static id to delete the points.
  2. Deleting Points from a Primitive Wrangle

    Here is another image kind of showing my progress .... What I want to do based on this data is randomly delete: 1 point on prim1 2 points on prim2 1 point on prim5 1 point on prim6 1 point on prim9 I underlined some points in the return value from primpoints just to illlustrate possible points to delete.
  3. Hi Guys, I am trying to learn more VEX and I am definitely in need of some assistance here. This is very basic. I have stacked rows of curves that have 3 points each. I want to delete from 0 to 2 pts per curve randomly. Curently I am assigning an @del_qty to each primitive that will tell me how many point on that primitive I am to delete. I dont know how to delete the points using a wrangle since my @del_qty lives on the primitive. Below is an imag that show what I am attempting to do (the red x's are deleted points). .
  4. 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.
  5. 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
  6. access menu item

    that is exactly what I thought you were going to say =P ... so a wrapper seems like the best way.
  7. 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
  8. getting active input from a switch node ?

    better than just listing an answer !!! thanks !
  9. 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.
  10. 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.
  11. 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
  12. 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. =)
  13. 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
