Instance textures from a replicator when you don't know how many textures there are

[nerk]

I need to do some texture indexing like this:

numFaces is a channel that indicates how many faces are detected in a video feed.

item[0-*] are Crop TOPs that are generated by a replicator.

Instance textures seems to only want to work with numbers like item[0-5]
but I may need more or less than 5…

How can I accomplish this?

You can just use item*, assuming you are replicating the number that you actually have. Otherwise you’ll need to build up that string using a python expression
'item[0-' + str(someReferenceToGettingNumFaces) + ']'

ah! item* works perfectly!
