Link to invisible parameter

[KeenTools]

Hello, is it possible somehow to use in expressions an invisible parameter of an effect? I have in my effect a parameter which is marked with PF_PUI_INVISIBLE and I want to use it in an expression.

My guess is no, just based on experiments with "INVISIBLE"=true parameters in pseudo effects. Those you apparantly can't access by name, match name, or index.

It's possible to have expressions on invisible params but I'm unsure if other expressions can then link to that hidden param.

Perhaps it's possible if you unhide the param, setup the expression, and then hide it again? Or will that give you an expression error?

i don't see why not. you can refer to in the expression by it's name or index even though it's invisible. is that not the case?

Thank you, everyone for replies. I've made some experiments: I can't use an invisible effect parameter by name or by match name (I've got an error that property is missing or doesn't exists), but I forgot to check access by index and it worked. An invisible parameter can be accessed by its index.
