    Pretty cool!

    I wish there was sound.

    Thank you SRBell,
    I´m not English native speaker, so I´m a little shy about my pronunciation... maybe next time I try to record with voice!
    best!

    You might get faster results instead of copy stamping the spheres if you just randomize pscale and N on the copy points

    TheProgg, can you explain better how to do this in the copy points? that´s separation of the copy nodes make me a little confuse.
    best

      @Patrick

      there are some "hidden" attributes that lots of sop's are using..

      if you create them on your points (attrib create or point wrangle) before copy node, copy will use:
      @orient (4 floats, quaternion)
      @scale (3 floats) or: @scale.x, @scale.y, @scale.z
      @N (3f, vector)
      @up (3f, vector)
      @v (3f, vector)
      @rot (4 floats, quaternion)
      @trans (3f, vector)
      @pscale (float)

      you can randomize those params in some range of values on point basis..
      like:
      float min = 0.6;
      float max = 1.2;
      @pscale = fit01(rand(@ptnum), min, max);

        Thank you so much, I´m still a noob in Houdini and are a lot of secrets to learn :)
