Description

@B4rr3l-Rid3r

Custom Node Testing

Expected Behavior

Create an image

Actual Behavior

Creates noise

Steps to Reproduce

update ComfyUi apparently further tham 0.3.46 and use any of the Flux model variations (DEV/Kontext/Krea)

Using 0.3.49 + Pytorch nightly

problem lays on ComfyUI using by default: --use-pytorch-cross-attention

changing to --use-quad-cross-attention apparently solves the problem.

Debug Logs

all good and same log as always except using Pytorch cross attention by default

Other

problem lays on ComfyUI using by default: --use-pytorch-cross-attention

changing to --use-quad-cross-attention apparently solves the problem.
