Obligatory obvious first feature request: Fully support SDXL #1

Closed tildebyte closed 1 year ago

Does an error appear when you try it with SDXL?

tildebyte commented 1 year ago

I was going to do that later today :D

ssitu commented 1 year ago

I can’t imagine why it wouldn’t work, I don’t think SDXL changed anything about the sampling process.

Looks good - great, in fact.

If start_at_step were exposed, we could use the Restart Sampler with the SDXL Refiner as well.

Glad to hear. I plan on making a node similar to KSampler Advanced after I finish making a node that implements FABRIC.

I was going to mention the "add_noise" and "return_noise" settings, but it's actually better at producing base images for the refiner to consume than the "stock" Comfy sampler, which I can't get to produce "soft" enough images - the refiner always ends up overcooking them.

Sample workflow (this is still WIP, so some settings will probably look weird)

Thanks for the amazing node, and the quick turnaround (the paper was submitted 26 Jun 2023! 😲)
