I love it; it’s one of the best models ever created. It works really well with hyper-realistic LoRAs. I hope to share plenty of images made with it soon.
Do get clear results with this checkpoint?
@21omen266 Of course! I love this model!
It looks so awesome, but my pictures come out all milky. As in "there is a milky filter over the picture". Any idea what I do wrong?
Follow-up to my earlier comment: I got it working. The problem was the VAE. With the baked-in VAE the images come out washed out, low contrast, with scattered noise specks. Loading the official SDXL VAE separately (VAELoader → VAEDecode) fixes it completely. Same behaviour on UltraDreamNexus v10 (fp32) and NDREAM ULTRA (fp16), so it looks like it comes from a shared source in the merge. Might be worth a look. Great model otherwise.
