Hey forum,

I've created a raster calculator model that includes two input variables and produces a single output raster. Now i want to quickly do that calculation over all 90 variable pairs times 8 folders. Model builder only lets me have one iterator.

For simplicity sake:

Let say the calculation is: RasterA + RasterB = RasterC;

now I want to do that calculation for 90 paired (RasterA and RasterB) variables within a folder. I am unfamiliar with python, but I have the time and resources to learn it. Any ideas??
