Hello

I have a transform node in the 2nd input of a vopsop.
I refer like so ch(“../xform1/ry”) to get the value of the ry channel.

My problem is I need to use my vopsop with a lot of transform although I need an expression to replace the name of the transform node dynamically.

ch(“../`opinput(”.“, 1)`/ry”) doesn't work
ch(“../”+`opinput(“.”, 1)`+“/ry”) doesn't work
ch(`“../opinput(”.“, 1)/ry”`) doesn't work
ch(“`”../opinput(“.”, 1)/ry“`”) doesn't work

no more idea guys …
is it a backquote thing ?

thanks for your help

You can try this:

ch(“../”+opinput(“.”, 1)+“/ry”)

It works !

thanks
