  1. Hey guys, I'm trying to do some kind of Oil + Water Flip Simulation.


    I have no idea how to do this Fseparation between Oil and water.

    I think it's not just different viscosity or?

    How do I set the oil - is it surface tension?

  2. Hej guys,

    I got a 3d object with final Redshift-Materials in a C4d scene.

    I wanted to transfer the Object with Shaders to Houdini and created a Redshift proxy and imported it into Houdini - works great.

    Is there any way to “unpack” / “convert” the redshift proxy in Houdini without losing the Shaders?

    I wanted to deform the proxy geo in Houdini.  I tried to unpacked + converted the proxy file so I can pointdeform the proxy.

    Unfortunately, all my materials and Shaders have been gone.

    Is there any way to get it working without rebuilding the shaders from C4d?



  3. Hej guys, I was trying to attach a fem object to an wire solver ...with no luck.

    I wanted to achieve something like a „Pendel“  with a fem object attached.

    i know it’s easy possible in vellum , but it’s was to unstable.

    Any tips here to achieve this?

  4. Hey guys, is there any way to get ragdolls interacting with flip fluids? 

    I was trying to let some crowd agents to float on on the fluid surface with no luck.

    They usually started to explode and fall sport when they hit the surface.


    Whats the best workaround there? Is that even possible ?



    best jack.




  5. Hej guys - I am looking for a way, to add a goal position for flips after a specific time.


    What I basically want:

    the fluid is "falling down" ......after 50 frames.....flow back to the initial state ( but dynamically -  each point exactly to its original/initial start position)


    I know this is well possible with grains via these attributes:  

    targetP , targetweight ,targetstiffness


    With "popsteer" and "popattract"  i could not got is work, because the particles never really stopped moving smoothly.


    I attached the file:scene.hiplcscene.hiplc




    Some an idea?

  6. Hej guys- I am looking for a way, to move the pivot of a "transform node" to the bottom of the of an animated! geometry.


    What i tried:




    It's working, but only in the first frame - since my object is moving the left - the pivot don't move with the sphere. 




    Any ideas?

  7. I'd like to know the best way to use If Else type statements in Vex code.

    What I wanted to achieve:

    if( in the group name "inside") {
        @stiffness = 1;
    else ( not in side the group name "inside") {
        @stiffness = 1000;


    What's the correct vex code for this function Vex?


    I don't get this working.









  8. Hej guys - I am cutting a tube with a spline. 


    Now I need to make this cut exactly on another geo:




    The problem is, that I have more pieces on the new object ( 2 secons picture).

    Is it possible to transfer the amount and order ( name, piece)  of the " cuts"  1:1 to the second object?

    So that the second object has also just 7 pieces ( instead of 14)?
