Hello, I want to control pscale (or "widths" in usd naming)on the lop level. I've written wrangle to do so. I am not sure if my understanding of syntax is correct. When I use code as in picture one, everything works fine but those arrays are not comfortable because I want to use Ids as seed for randomization. Then I've tried run on elements checkbox, but I can't make it work, any suggestions about syntax?

for the second one, the functions usd_attrib and usd_setattrib are still going to be array-based. To set a single value, use a bind instead.

e.g.
@widths *= 0.1;

Yeah, but I've already randomized pscale thats why I am multiplying and I dont want to use single value. There was pscale set in sops before exporting to usd, but wrong scale and during lookdev I want to change, it as well as randomize a little bit more (bigger difference between samllest and largest).

Thats what it does when in run over elements of an array. @widths binds a single value from the array for each element of the array and executes the code on each.
