Hi,

this seems weird, since I could have sworn I used to do this a lot and it always worked, but I was having trouble referencing Attributes of other nodes the other day.
for example, inside a Wrangle node, I'd write:

i@attribute = detail(“../counter”, “numiterations”, 0);

where I renamed the meta import node of a foreach loop to counter. I tried it with the 0 argument at the end and without, nothing seems to work, even autocomplete doesn't show me a list of nodes on the ../ level. It all work in Channel expressions as expected though.
What am I doing wrong?

Cheers,
Ivan

I don't think you can do relative references like that in a vex call. Connect the usual way and use the 0,1,2,3 syntax, or create a spare input, put the relative or absolute reference in there and use -1 as the geometry reference instead.

Thanks, that makes sense. I'll do it like that.

You can do what you want. You just need to use the op: reference.

All that typing though.

i@attribute = detail("op:../counter”, “numiterations”, 0);

Works like a charm! Thanks a lot!

use spare inputs, it will track dependencies and work in compiled networks

A wrangle already has multiple inputs and they have no predefined function. Just plug in the second input from the left and use i@iterations =detail(1,“numiterations”,0);

How to do this in a Snippet VOP?

P.s. I know you can use Parameter VOP, but I kinda ask this in relation to my comment right here :$ : https://www.sidefx.com/forum/topic/73545/?page=1#post-310869 [www.sidefx.com]
I'm in COPs so no real possibility to use a direct Wrangle.
