Hello there, my name is matias and im new to houdini. im following a tutorial about abstract effects. and im trying to use a copy stamping node to make some flowers

when i try to randomize the values (rotate, scale) i get this error:








the expression im using in the group 1 of the copystamp node is: fit01((rand($PT*20)*2).0.0.5)

i would like to get a random size in all the spheres, how could i fix that?

thanks and sorry for bad english.

It's hard to say what your problem is since you didn't post what the stamp expressions you are using are, and where they are used. What's on the other end of the object merge, a point cloud?

On a more general note, we don't really use copy stamping anymore, and particularly not for transforming copies. Using instance attributes (pscale, trans, orient, pivot, etc) on template points is much faster and more convenient since you can use vops/wrangles/attribrandomize/etc to modify the attributes however you like.
