Hello gurus. Today's question is something that I feel I'm close to figuring out but not quite.

My set up is simple, Box, Copy to Points, a Grid and finally a Point node to define some parameters.

I'm basically trying to figure out if I can randomize the height of my boxes strictly through the Point attributes.

I can get somewhat in the general vicinity of what I'm trying to do by using the Scale attribute and a rand function like this: value * float(rand(@elemnum))

However I would like to be able to control specifically the size randomness in x, y or z independently. As it is right now, it is applied uniformly to all of my geometry so that while I can achieve the variations in size, the geometry is scaled in x, y and z simultaneously.

So for instance, let's say I wanted to keep the x and z scale the same, but randomize the y scale from point to point in my grid.

Any ideas?

You can take advantage of the vector signature of random, and use swizzling to keep the x and y components uniform.

a little less scary way to set just random z scale for example may be

or then switching to Attrib Wrangle allow you simpler workflows like

Thank you both, awesome solutions! This is why I love this place.
