  1. 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
  2. FEMgravity field not working

    not possible?
  3. 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
  4. 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
  5. 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
  6. velocity fields for grains

    anybody still have an idea? i found a better example for this:
  7. 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
  8. 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.
  9. 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
  10. cloth and rbd interaction

  11. 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 ;-)
  12. FEM / CLOTH - Target GEO

    Thank you this is working...but not with an animated noise. Do you know if this is possible too?
  13. 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?
  14. 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
  15. Does anyone know how to setup a vdb morph with the " vdbmorphsdf "- NODE and a mask? Never got it working. Best
  16. 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
  17. 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.
  18. 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
  19. 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?
  20. 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

    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

    wow - really cool - is there also a way to define the falloff? @konstantin magnus
  23. procedural walk rig

    Hello guys - does anyone know how to build an procedural walk rig or have some tips to how to get something like this? best
  24. procedural walk rig

    Thank you very much guys, i followed this tutorial - but i had some problems to rebuild it. Could be a version problem between H11 und H15. @rich_lord is your setup working in H15? best
  25. Hello guys, i copying geo on a spline und control the scale of the copied pieces with a ramp. (picture 1) Now i wanted transform each piece to the "ground" - the bottom border of each peace, should be at the same height. (picture 2) How i could do that? best! copy_222.hipnc
