In my test scene I am creating a point attribute called “myAttrib” via a Wrangle node named “createAttrib” and assigning it a float value of 2. I'm then attempting to use that attribute to drive the Scale Y parameter of a downstream Transform node with the function:
`point("../createAttrib/", 0, "myAttrib", 0)`
I get an error on the transform node:
Unable to evaluate expression (Syntax error(<node name>)
I've also tried it with absolute SOP paths, and in the same test scene I'm trying it with a detail attribute / `detail()` expression, but same error.
So, how do I go about driving a SOP parameter via SOP attribute? I've seen references to using Parameter VOPs to bind outputs but after playing around with that and reading all the manual pages I feel like I am definitely missing something, or maybe misinterpreting this method entirely.
Any help would be appreciated learning the correct method of accomplishing this. Thanks!
