Genfocus’s Flux1-dev refocus workflow keeps crashing on a 3090

ReasonablePossum_ · reddit · 2026-07-25

The author found Genfocus, a depth-based deburring and focus / depth-of-field shifting solution built on Flux1-dev, plus a ComfyUI workflow for it.

They tried to run it locally, including with smaller Flux variants, but kept hitting GPU memory crashes instead of a working setup.

The post asks whether anyone has successfully run the workflow on a 3090, and points to both the GitHub project and a related ComfyUI refocus workflow.
