This is the flow I use to generate realistic movie posters with my Lora: https://civarchive.com/models/746729

I'm running this locally and it takes a few minutes per image on a 3090. This is all tuned for maximum quality, but if you want faster generation times, there are a few things you can try:

• cut out the upscaler

• reduce flux resolution

• don't use the fp16 model

There may be a bunch of nodes missing in your ComfyUI install. Easiest way is to install ComfyUI Manager and then 'Install Missing Custom Nodes' in the Manager Menu.

Requirements for Flux:

Example Prompt used for the Bioshock poster:

A realistic movie poster in the style of MV144, featuring title text 'Bioshock' and subtitle text 'Sins of Rapture'. The central figure is a Big Daddy, his massive diving suit illuminated only by the soft glow of his helmet's lights, standing amidst the flooded ruins of Rapture. His drill is lowered, and beside him, a Little Sister gazes out over the broken city, as if questioning the life she has been forced into. In the background, half-submerged art deco skyscrapers stretch upward, but cracks in the glass walls reveal the dark waters closing in, threatening to engulf the city. The ghostly figure of Andrew Ryan appears faintly, watching over the destruction he helped cause. Fish swim through the broken windows, while faint whispers of long-lost citizens echo through the halls. The mood is eerie and melancholic, focusing on the untold secrets of Rapture's downfall and the moral consequences of its creation.
