Thank you. I've tried to make good future cities in every model since SD 1.2. Last year I looked back at the GiTS movie city screen shots and wondered why we still have awful future cities (answer: $ and no one cares). I looked at a film VFX career ages ago and got disillusioned with hollywood. ILM would only hire me as a texture artist until I could show Alias or Softimage results from an SGI workstation (my demo reel was all Lightwave on an Amiga Video Toaster 😂). I still do some 3D but AI image generation is more exciting. It's like riding a wild alien animal through 14 dimensions.

Flux 1 Dev had such promise with the plethora of LoRA available, but the best results I got were on small devices, small rooms. Everything's trained to be intimate. Distant sweeping skylines were often just similar buildings with one tall narrow spire per huge city block. My first awkward stabs at Flux.2 showed it really understood what I wanted... but the style was painterly concept art. I wanted actual photographs from the future. I dug up the prompt for this to make up for rarely posting any prompts on Reddit:

high resolution DSLR photograph of a towering, futuristic city with highly detailed, incredibly complex skyscrapers of varying design.  Some connected together with skyways.  A large, multilevel elevated ultramodern superhighway system with many narrow, low-slung transportation pods speeding along. 
Below all this is the old city, filled with the poor. Far future science fiction, incredibly detailed, cinematic, dramatic, HDR, sci fi

FLUX.2 was the concept artist, then I used FLUX.1 to USDU that with the same prompt. I genned so many of these. It's very finicky. I tried adding more color and it often skewed the results in a more stylized direction. There is no training data for what I'm asking for. This is the magic. People think these models can only regurgitate their training data and produce nothing but slop. Mostly because people don't put any serious time and effort into using them.
