Run flux with negative prompting via 2 different methods in ComfyUI. Tested on a 16GB RTX A4000 and the fp8 dev model. Affects performance dramatically - approx 2x slower with Dynamic Thresholding, approx 3x slower with Perpendicular Negative Guidance, but it works.The Flux.1-schnell and merged dev-schnell models don't appear to be compatible with either method.Demo pics: Prompt is "4k photo, high quality, in a European forest," Negative Prompt is " "path, trail"
