Again, apologies for the simple question - still out of practice.

I'd like to control a switch VOP based on whether or not a top level HDA parameter has an filename entry (string) or not - what am I doing wrong?

In the “index” parameter field in the switch VOP:

strcmp(`chs(“../../../parameter_entry”)`,“”)

It evaluates properly in the texport when I cd to the op and change the entry from something to nothing in the top level interface, just not in the switchVOP itself. What am I missing?

t

remove ticks:


also kwwp in mind that if you are putting this directly in the switcher parameter of the Switch VOP it will not be animatable, if you need that functionality, promote the switcher parm

That was it - great, thank you!
