  1. Hi i am emitting crowds every 60 frames with the impulse activation "$F%60 == 0" in the crowdsoure. Now I have the problem that my ragdoll constraints are just appearing in the first emitted ragdolls. All that comes after don't have the ragdoll constraints anymore and the parts fall apart. Is there a solution for this? All the best and Thank you! jack
  2. vellum - target position - dynamicly

    amazing tomas!
  3. Hello guys - may its really simple, but how can I animate a soft/dynamic movement transition to the starting point of my vellum animation? should go dynamically - not with blendshapes! Basically like the targetstiffness/ targetposition we have in gains. Is that possible with vellum? I uploaded a file... Thanks back.hiplc
  4. vellum - target position - dynamicly

    ok - one more question: how can i use a separate goal/geo which is animated? How can I change the link to to a "self-made" goal?

    perfect. thanks
  6. vellum - target position - dynamicly

    Thanks - Atom. I dont wanted to touch/animate any forces, because my scene is way more complex. It should move/morph to an specific target/rest position - or even better - an animated restposition. Is that possible with vellum? Its the same like the "Cloth-target" in the older houdini versions. Like here:
  7. Hi, i am emitting vellum geometry over time. My problem now is that i can not add the hires geo back to every emitted (new) geometry. It just working with the first one. I was trying to do something in the foreach loop with no luck. Is there a simple solution for this? BTW - i uploadet the file also All the best for each.hiplc
  8. Hej guy i wanted to remesh my geo in a specific direction. Is there a way to do this with splines as an direction or anything else? Whats the best approach for this? All the best. remesh.hiplc
  9. Hej guys - im trying to rotate an agent clip 90 degrees with an transform note. But this transformation did not align in the crowd simulation itself... odforce.rar Does anyone has a simple solution how to do it? BTW- i attached my scene

  11. Grain Break + Mesh Break

  12. Hej i found a cool video on vimeo: I was wondering how to achieve this effect. At the first moment it looks like a hires model with a lot polygons which got displaced? But i'm not sure here.
  13. Grain impluse activation later

    Hello guys, i have a grain sande box with is starting to simulate at the first frame. I need later after 600 Frames. In the " impulse activation tab" i have here $SF==1 What should i add to activate it at frame 600? Best jack
  14. Hi - i created particles colors with the Attribwrangle VEXspression: // Color from Bounding Box @Cd = relbbox(0, @P); this code basicly created a bounding box based on all particles positions in the scene. (it changes the color - because the particle are moving in space) How to define an own bounding box (size of the bounding box) - based on primitive-cube for example? All the best bounding_box.hip
  15. Pop attract with grains

    Hello guys, I wanted to use the pop attract in a grain simulation. I have a simple simulation with grain, which are falling down. After a specific frame I wanted to let the particles go back dynamical to the exact start position. I thought it’s possible with the pop-atttactor node. I’m the source tab, I can choose atttaction type: particles. Here I link to the rest position of the first frame of the grain particles. This doesn’t work for me. All the best jack
  16. Pop attract with grains

    i added my file.... Is it possible to add a target position to the grains like "fem" or "cloth" has? best jack grain.hip
  17. Hello guys, i wanted to delete some points on a spline - my problem is that the spline always wanted to close itself and adds some bigger splines between the gabs ( i don't want it) . How can fix it? all the best delete.hip
  18. delete points on spline -> do not close

    no - not working :-(
  19. Hello guys, is it possible to drive the strenght of the smooth sop based on attributes (color)? I was trying to type from vex expressions..but he did not use it.
  20. Hi, i have a copy stamp and wanted to build a look at function for the copys to a specific point or geometry - the rotation for each copy should be applyed only on the Y-Axis . Is there a special node for this? How does it work? all the best. jack look at.hip
  21. Hi, someone know how to setup a defined gravity field for an FEM simulation? I tied it with a mask field in the gravity note but it doen't work for FEM ( with an RDB Object it works perfectly)? Scenefile is attached: thanks so far! FEM_GRAVITYFIELD.hip
  22. FEMgravity field not working

    not possible?
  23. Points from Volume

    Hello guys, i was looking for an option to drive particles(point) like a pyro Animation. Is there a option to do this in Houdini? I know that Houdini has a points from volume - node...but these is static an change the position on every Frame. Is there any solution for it? best jack
  24. Hi, i was trying to group particles from a flipfluidobject, but without luck. My goal is to add to differnet gravities with 2 Popforces + 2 PopGroups. The particles from the left half of my flipfluidobject should have a positive gravity and the right part should have a negative grafity. Does anyone has an solution for this? best force_Group.hip
