Now that we are done with our Depth-based tools, we can Scale it down to its target resolution to get our Antialiasing. Here you see I've chosen B-Spline, out of the many options Fusion gives us for reducing and enlarging. I'm using "B-Spline," stylistically because of the softening effect it also has when affecting an image. (Whereas if I'd wanted to preserve the sharpness of the render, I'd have chosen, Sinc, Catmull-Rom or Lanczos.) I've also copied-and-pasted an Instance of this Scale tool because I'm going to next be working with the Spec channel which in this image doesn't need to worry about Depth-based issues, and attached right at the head of the flow, will keep the subsequent tools quicker by working with smaller amounts of data. (Pasting an Instance means that whatever is done to one, will be done to the other... so it's a quick way of getting the exact same settings between tools.)

Now, I've copied-and-pasted the original Loader again, (renaming it "Spec",) setting its Color Channels to be the Spec, R/G/B channels saved by exrTrader. (I've deactivated Alpha, Z, and all the others since I won't be needing them to do what I'll be doing with this part of the flow.)

 

 

NOTE:
I've also gone into the "Spec" Loader's, Import tab, and setting the Depth to: int16, since I find the Highlight tool we'll be adding gives me more controllable results in compositing over other images when its source image is Integer-based.
