  1. Hello guys, i would like to give an big scale of disturbance in my smoke simulation, and an fine details in thinner areas. in good old days i would use two difference scales (gas disturbance) and merge them. but looks like in Houdini 18 the gas disturbance was replaced by the so called gas disturb, it seems both do the same thing. however the parameter cutoff(if i not wrong, it's the area where the disturb would act, using the value of density) Is no longer available. and there is a Threshold Range, but i didn't fully understand how read this value and use it well. how use those parameters well, like how i read these values to put in Threhold Range
  2. (Solved)Rigid Bodies active by geometry

    wooow that was a crystal clear solution bud! the explanation concerning the sopsolver/solver sop. was awesome. and apparently the vex function max is doing the magic. thanks!!
  3. hello guys, i with a scene that has an moving tire, while it pass the on the surface the gravel begin to fly and blow away. i scattered an bunch of geometry into the surface. in the dop level, ive used SOP solver in pre-solve to give the active=1 to the points(and "hold" the active 1 using an solver) but none of this shit worked, ive messing around and debuging the spreadsheet with no luck att all, i lost. Thanks ps: i will attach an simple setup of this active_by_geometry_v00.hip
  4. Hello guys i having trouble while doing this process: I use an incoming modelled piece geometry to boolean an moving alembic. the ideia is one of the debris piece fall with an normal gravity. while the moving geometry stick with the booleaned shape. i was messing with point deform nut no luck at all. i dunno if it a bit complicated if need i can provid an simple setup of the question. thx
  5. RBD varying mass Help

    Hello guys ive an very simple setup, of sphere jumping. however i would like to variate the drag of each piece(not using the initial velocity) is that possible?? i was messing with mass but still not figuring effectively how it work in solver thx ps: i will attach an simple exemple vary_drag.hip
  6. (Solved)RBD Solver-Active pieces in an location HELP

    hmm i thought the dop would read automatically those incoming attributes from the geometry level. definetly gonna try that ed: It works perfectly!! thanks Hernan
  7. Hello guys, the scene has an simple moving geometry, with a bunch of spheres scattered in this moving box. and i need to maintain this animation and when these sphere enter in certain area they fall (something like an ativador). I was messing with RBD Packed Object, it seems it has something with this tree integers attribute (active,animated,deforming). Using attribute transfer sop to change those values and the activator region looked good but it didn't work as expected. please any tips to achieve this?? ps: i will attach an .hip setup. activate_by_region_v00.hip
  8. Delete Post

    hello guys, i created an duplicate post, for the sake of organization of the community is there a way to delete an post
  9. (SOLVED)cut using a line HELP

    YAY THATS It!! you saved my day, thanks man i owe you a beer!
  10. Hello guys, i need to create two pieces of geometry for that i created a line that is the silhouette of each piece. however i not figuring an way to program that inside Houdini. please help me. ps: i will atach an simple setup to exemple the question.

  12. hello guys, ive a simple sphere volume with a bunch of points scattered in this sphere. i would like to decay the point number after frame 30. but not a clue to wrangle that. please help guys.
  13. PYRO: attract flame by geometr

    hello guys. i've a simple pyro flame simulation and i need the geometry attract the flame. but i not getting how to do that. please help me, thanks in advance. ps: i attaching an .hip file attract_smoke_by_geo.hip
  14. Hello guys i need to spin the points in wheel behavior. i created and xyz dist to determinate the area that it should occur but no clue how effectively make them circle. i was messing with pop spin but definetly didn't get an acceptable result. please help. ps: im attaching the simples setup. pop_radialspin_v00.hip
