  1. 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
  2. delete points on spline -> do not close

    no - not working :-(
  3. 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.
  4. 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
  5. 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
  6. FEMgravity field not working

    not possible?
  7. 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
  8. 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
  9. Hej guys , i was looking for an option to add costume velocity fields to a grain solver. I a a tutorial, but it did not work for grains. Does anyone has a tip to do it with grains? best jack
  10. velocity fields for grains

    anybody still have an idea? i found a better example for this:
  11. fem constraint

    Hi guys, is it possible to use animated contraints with Fem? I was trying to contraints the head of the 2 tubes (image) to an rotating cube, so that both tubes are winding together like a rope. With fem targets geo i had no luck. :-( Is this possible? best jack
  12. fem constraint

    yes i was thinking about this - but i'm not sure how to animate that in sop-level so that it looks like this: bend deformer does not working i think.
  13. Hello guys, i was trying to add a rdb-collider to a cloth animation...without luck. Is it possible to combine both so that hej interact physical correct? best
  14. cloth and rbd interaction

    up.
  15. Hello guys, I have a cloth object and addet a target object in the DOP Network. Is it possible to control the transformation to the target-object ( Target Stiffness) with a animated noise? Best ;-)
  16. FEM / CLOTH - Target GEO

    Thank you this is working...but not with an animated noise. Do you know if this is possible too?
  17. Crowd - Look at

    Hello guys, i am playing around with crowds in houdini. I wanted to achieve, that my crowdsource people are placed in a circle around a specific object - and all faces have to look at the object. Does anyone know how to do that?
  18. Crowd - Look at

    Hmm, no no chance to get ist working. I also try the self tool "look at". The people are not looking at my object. ..hmm
  19. Does anyone know how to setup a vdb morph with the " vdbmorphsdf "- NODE and a mask? Never got it working. Best
  20. Hello guys, i am playing with crowds in h16. I have 2 states: one standing and one walking state. The problem: when i am blending from the walk to the stand state, the chraracters still moving forward. How can i kill the velocity of the stand-state? Best jack
  21. Hello guys, is it possible to transfer Points UVs to Primitiv uvs? I have Grain Particles with Point UVs ...now i wanted to transfer the UV information from the Points to Primitivs (Surface) so that i can export an alembic to C4D. I tried Attribute Promote..but the uvs are not correct afterwards.
  22. Hello guys, i have a a object filed by a grain source. My problem write now: How i can apply gravity (with popforce) only to particles which reach a specific speed/velocity? best
  23. Hello guys i have a polygon-selection as a group (picture a ). Now i wanted to smooth out the polygon-selection so that the points i get a nice circle shape (picture c) . When i try so smooth the group with a smooth-sop, i get something like in "picture b". Does anyone has a good approach?
  24. Hello guys, i wanted to open my FEM-Setup-File which was created in H15.5 , with the new H16. Now H16 showes me some problems with this setup. Does anyone knows where the problem comes from? best
  25. BLEND NORMALS

    Hello, i added a simple Spline und copied some rectangels on it. (PICTURE 1) Now i wanted to blend the normals, so that the bottom rectangels always have the direction of the ground (PICTURE 2) Does anyone know how i can do this? i posted my hip file aswell best spline.hipnc
