  1. 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?

  2. 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

  3. 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

  4. 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?

  5. 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?
