    float angle = fit01(rand(@ptnum),0,360);
    p@orient = eulertoquaternion(radians(set(0, angle, 0)), 0);

      float angle=radians(fit01(rand(@ptnum+ch('seed')),0,360));
      vector4 rot= quaternion(angle, @N);
      @N=qrotate(rot,@N);

      Hey man not sure if you're still active, but where abouts in the node setup would you put the attribute wrangle with this expression?

    Very well explained. Good to see an Aussie providing a tutorial -- our American friends seem to contribute 95% of them.

    Thanks for this, seems like SideFX finally put together an artist friendly scatter SOP in 18.5, long time coming...

    Hey thanks, it amazes me that after all these years nobody at Sidefx came up with the idea of making stuff like this less convoluted.
    Time for some AI to step in I guess ;-)

      Sidfx is continually evolving/moving target ....you have to keep up with it. This is because of a history of innovation and nowhere is it more apparent that you can actually get into the ground level, such as this tutorial is illustrating.
      At this point, there's now a "scatter and align" sop instead of having to use three nodes (sops) to build your rotations. Learn to use that "scatter and align" sop in your spare time.
      But this is a very well explained tutorial. It's actually not convoluted at all. It's just a part of embracing Houdini.

    I tried setting a rand_rot to randomize rotation but it doesn't work, why? I tried to use protate

    This is asinine how many tutorials and forums I have had to look through to find ANY answer that might work. This takes TWO SECONDS in C4D.

      That's odd because I've seen nothing but tutorials galore regarding the many ways you can orient objects onto others.

    but these are not instances, these are copies
