I was looking into the compositor for the first time, but I came across something that is an issue. There seems to be no way to view multiple outputs from the node tree.Both image viewers just show whatever the most recent viewer I clicked on is. Am I correct in this or am I doing something incorrect here? Comp_Example

You’re doing everything right. This is just the way Blender works.

Here’s how you can make it work:
1) In one image editor choose Render Result from the top-down menu. This will show output from the Compositor Node.
2) In the other one choose Viewer Node to see output from selected Viewer Node.

As you noticed, Viewer Node only shows the last selected one. It’s a limitation of Blender.
However, you can use Split Viewer Node node to get side-by-side comparison.

Note: Blender Compositor has some slight limitations, but hey, it’s free :).

    $\begingroup$ "Note: Blender Compositor has some slight limitations, but hey, it’s free :)." That's a definite plus. But I'm looking at this for our studio, so it's needs to meet certain standards if we're going to use it ;) I tried what you suggested but the Render Result is showing nothing. Hopefully the compositor will get some attention and have things like this addressed :) $\endgroup$ – Anti-Distinctlyminty Oct 30 '19 at 8:31
  • $\begingroup$ @Anti-Distinctlyminty I share your pain - Blender Compositor would seriously deserve more friendly UI. That’s why I switched to other software for compositing. $\endgroup$ – ᴊᴀᴄʜʏᴍ ᴍɪᴄʜᴀʟ Oct 30 '19 at 8:39
  • $\begingroup$ I've been very impressed with Natron. But it looks dead in the water, which is a real shame. $\endgroup$ – Anti-Distinctlyminty Oct 30 '19 at 8:45
  • $\begingroup$ Some people use DaVinci for compositing, as it supports EXR files and is also node based. I believe Blender Compositor could learn a lot from their UI. $\endgroup$ – ᴊᴀᴄʜʏᴍ ᴍɪᴄʜᴀʟ Oct 30 '19 at 8:56
