Maybe I was overthinking this. It looks like Merge2 is a special case with its dynamic number of inputs, and so no matter how many inputs it has, mask is always input index 2. I swear I found a scenario where it wasn't, but now it appears to be reliably so.
Anyway, sorry for the noise. Cheers, Ean On Jan 8, 2013, at 8:30 AM, Ean Carr <eanc...@gmail.com> wrote: > Hi all, > > Anyone found a reliable way to get the index of a node's mask input?
