comfyanonymous 0a6b008117 Fix issue with some custom nodes. 7 months ago
comfyanonymous 56f3c660bf ModelSamplingFlux now takes a resolution and adjusts the shift with it. 
If you want to sample Flux dev exactly how the reference code does use
the same resolution as your image in this node.

Lower SAG scale step for finer control (#4158) 
* Lower SAG step for finer control

Since the introduction of cfg++ which uses very low cfg value, a step of 0.1 in SAG might be too high for finer control. Even SAG of 0.1 can be too high when cfg is only 0.6, so I change the step to 0.01.

* Lower PAG step as well.

* Update nodes_sag.py

This lets you adjust the guidance on the dev model which is a parameter
that is passed to the diffusion model.

comfyanonymous 66d35c07ce Improve artifacts on hydit, auraflow and SD3 on specific resolutions. 
This breaks seeds for resolutions that are not a multiple of 16 in pixel
resolution by using circular padding instead of reflection padding but
should lower the amount of artifacts when doing img2img at those
resolutions.
