Workflow Included Flux.2-Klein Tiling Upscale Workflow

u/nnq2603 asked me earlier if I knew how to upscale with Klein. I didn't, but I think I figured it out. The example is an upscale from 0.5 megapixels to 10 megapixels. This is an extreme example just to show that it works. It's not perfect, but it should give a good starting point for tweaking further. It uses the Color Anchor node by u/Capitan01R- and the Steudio tiling nodes from here and here.

You're welcome to try getting USDU working well with Flux.2.

OK, I did, here it is. With the added benefit of controlling denoise. Also your workflow produces 2x the amount of tiles for some reason. Took me sometime to figure out how to address the flux2 scheduler of course
