I don't know why copyGroups are not created for each copy of the object being copied in the hip file created….

What I what to do is vary the height of the box being copied in random way.

Thanks!

Hi,

You will need to use copyGroup$PT instead of the default copyGroup$CY to get each box that is copied to be in its own group.

To vary the height of the boxes being copied in a random way, you can make use of copy-stamping in the Copy SOP to do so. I have attached a modified hip file for your reference.

Cheers,
tk

Hi oat,

You're most welcome. To have the random pattern animated with time, you can insert a $F in the ‘height’ stamp variable. $F is the current ‘frame’ number.

I have attached the animated version of the file for reference.

Cheers,
tk
