i have created a new multiparm folder
inside i have 2 parameters
toggle get_path#
string path#
i have set default value for the second parameter:

`ifs(ch(“./get_path#”),opsubpath(“./obj#”),“”)`

i expected to get this after adding 1st instance of parameters:
`ifs(ch(“./get_path1”),opsubpath(“./obj1”),“”)`
second
`ifs(ch(“./get_path2”),opsubpath(“./obj2”),“”)`
…

however i got this
`ifs(ch(“./get_path#”),opsubpath(“./obj1”),“”)`

no matter how many “#” symbols i used in my expression, only the last one is evaluated as an instance number
any help?

please, anyone?

can you at least tell me if it should work that way?
can this be considered as a bug?
or am I doing it wrong?

It sure looks like bug to me. (please report it).

As a possible workaround in the meantime, you could try an inline function instead of the `ifs()` expression… something like:

`{ id = #; string out = “”; if(id) out = opsubpath(“./obj”+id); return out; }`

Although it looks to me like that call to opsubpath() will always give you what you already know, namely: “obj#”…. and if that's true, then you could just turn it into:

`{ id = #; string out = “”; if(id) out = “obj”+id; return out; }`

But maybe there's more going on that I'm missing.

HTH.

Each # in the expression refers to the instance index in a different nesting level of the multiparm. Since you don't appear to have any mutliparm nesting going on, only the last # will be affected. Mario's solution is likely the only way you can get this to work.

Thank you Mario and twod !!!

inline function is working great!
i didn't know something like this is possible
I can't find it in documentation
can i call For loop from inline function?

i tried For loop in python, but it seems to me that i can't set multiline expression as a default value of a parameter


ps: opsubpath() returns more than an object name, because i am calling it from an asset and i do not know its name, or name of other parent assets which all i get by opsubpath()
i am using the return string as an reflection mask
but anyways it works, thanks a lot
