ControlNet Union ProMax and More! (Patreon)

So many new things, so little time!

PixArt Sigma 900M, more playing with the new samplers & schedulers, a better version of rembg and of course the new ControlNet Union ProMax model!

As you've probably seen in the previous bonus workflows, I do like the new Euler cfg++ :) While I originally went up to 50 with it using a very low CFG, slapping a perturbed attention guidance node into the mix changes that. It seems to behave slightly differently to the other samplers, bringing out more details is just 6-10 steps... with 12+ steps usually overcooking it!

We don't need custom samplers for GITS and AYS any more, making life easier :)

The new RemBG is a no-brainer. Easily better than the old one and can be a drop-in replacement for any workflow using background removal.

ControlNet ProMax Union is awesome and now works great in ComfyUI. Pick the mode you want to run in (or auto) and use as normal!

(Update) Nb. It's actually https://github.com/pamparamm/ComfyUI-ppm which is now adding the new schedulers!

Also worth a look, though not included in the video, is this upscaler:

It really does bring out those details, so works best with more photo-realistic generations.

Workflows made for the video are also attached below!

Ps. you can use the IPAdapter node to inpaint look-a-likes too ;)
