As Frank mentioned, you’ll need to go to TCL to do string comparisons. For what
you’re after, you can use:
![string equal [value Shuffle_CHANNEL_SELECT.in] "rgba"]

try [value Shuffle1.in] instead of Shuffle.in to get the string.

I'm guessing this is because rgb and rgba are references to the same layer,
though it is inconsistent to the way other dropdown menus work.

Hello Nukesters-
Im trying to expression a Switch node (.which) based on the pulldown from a
Shuffle (.in). I see that this is possible if you treat the Shuffle pulldowns
as their numeric inputs:
Shuffle_CHANNEL_SELECT.in==1?0:1
(works great, with the caveat that both rgb and rgba are treated as 1)
but I'm wondering if this can also be done by using the actual string in the
pulldown, like 'depth', etc:
Shuffle_CHANNEL_SELECT.in=='depth'?0:1
(ERROR: Switch.which: missing ''' in "Shuffle_CHANNEL_SELECT.in=='depth'?0:1")
- I've tried a range of syntaxes but haven't figured out how to make strings

- Also is it an intended feature to treat both rgb and rgba as input 1? In

Thanks in advance for any pointers!
