I don't use weights for my light2x prompts. Doesn't seem necessary most of the time.

Trying the ultrawan 4k Lora gave me invalid dimension errors and eventually oomed 96gigs vram. Attached is the result of the 1k lora. It used about 50 gigs vram at peak and took 300 seconds with the NAG + light2x workflow. Kinda hard to review it for quality since I'm phone posting. Seems ok.
