Hi Houdinists !
I'm a TOPs beginner playing with PDG, I'm trying to load 2 different files : Source A and B and make operations between those 2.
I can "call" one source file inside a ROP composite Output and make fun with it : no problem ! But I need to call 2 sources at the same time : source A and B.
The idea : load image A and image B, make operation, for example : merge image A channel green with image B channel Blue, and export the result.
As I said : I can do it with one source (in screenshot with AO node works well). But I have no idea how to do it with two sources

After several researches, here the solution.
Very special thanks to Mel Massadian for the help
-use partitionbyindex
-create your ROP composite output
-inside the ROP, set `pdginput(0,"",0)` for the first file import and `pdginput(1,"",0)` for the second one.
-Do whatever you want inside ROP
-Enjoy !

Hope it helps !
