Thanks! I've made a video (I'll edit it tomorrow) doing some testing on getting SDXL to generate some realistic stuff. I did so much testing (did not use this method) and eventually decided that Ultimate SD Upscaler did a really good job on its own.
ah you're totally right the link was broken, should be fixed now. The get node works together with the set node. If you use a set node connect it to wherever you want your input to be set then name it. so for example, if I connect a "set node to my image output, and then call it "IMG" I can then use a "get" node to put into an img input anywhere else. Get and set basically work together so you don't have to drag a huge line across your whole screen.
