  1. I have a float attribute called "test" that retuns 0-1 If I want to use that attribute value on the parameter on my wrangle, how do I write the expression? I tried point("/obj/test", @ptnum, "test", 0) This expression doesn't error out, but returns the value of point number '0'. If I write point("/obj/test", 3, "test", 0) then it returns the "test" value of point number 3, but it just that @ptnum doesn't work. What did I miss?
  2. Copy Sop Problem

    If you uncheck 'transform using template point attribute' on copy SOP, it will work, but I think that's not the result you want. This happens when you copy volumes(ex - 'vel' field will be messed up, so that you need to rotate it afterward).
  3. How to upres Explosion / Fire simulation?

    Thanks, Bunker, for your answer!! I realized I had some different valueson my Upres solver, after changing that, and tweaking a bit helped.
  4. How to upres Explosion / Fire simulation?

    Um, I can't post hipfile
  5. I've done upresing the smoke-only simulation, but never done the pyro(with fuel field). When I tried to upres my explosion simulation, I get the similar shape/motion as my low res one, but not the same density/heat/temperature. I would assume it's because gasupres DOP doesn't have the 'gas released' parameter, which would work with my source volume and affect the initial density/temperature/heat of it. What am I missing in this work flow?
  6. Shading problem

    could you post a hipfile?
  7. Can you post a hipfile that addresses the example(fluid) that you are talking about?
  8. dropdown pointsfromvolumeSOP under your vdbfrompolygonSOP.
  9. Time Shift Node

    Use 'File' node instead of Dop I/O. Select 'No geometry' under Missing Frame parameter.
  10. In the edit parameter interface for Ordered Menu -> Menu Type value on Token and the name for Label. For example, -.3 for Token and High for Label. After apply, Mouse over your dropdown menu(ordered list menu), right click, and choose 'copy parameter' then go to the parameter of translate Y, right click, 'Paste Copied Relative References'.
  11. Space shuttle exhaust -

    Make a field that has the vector information (curl shape), and use the field to advect the smoke - Gas Advect Field.
  12. Flip Fluids Particle Dissipation

    I would! but I don't use houdini at home ever since it broke my Macbookpro graphic card once... and of course I can't post hipfile from work Sorry!
  13. Flip Fluids Particle Dissipation

    Use sopsolver or Geometry VOP to remove the points.
  14. This has happened before a few times. Let's say I have two geometry SOPs on obj level. I have only one of them turned on, and I am not viewing the other one(turned the blue visible mark off). When I scrub through timeline. It starts cooking the turned off geometry SOP. My quick fix is just putting Null SOP inside of the "supposed to be invisible geometry SOP". Is this a bug? * I am not rendering any images on Render View or anything.
  15. BATCH RENDER REGION

    I am not sure how do you mean by.. .region maybe black or empty? If you are just trying to render region, there's an option under camera parameter... something about 'crop' left, and right.
