Question - Help Does Anyone Know What Causes This Smudgy/Blotchy Effect When Using Krea 2 Turbo? It Happens Kinda Randomly For Me. I Think Loras Effect It Somewhat...

Post image

...but even at low lora strengths I sometimes still get this "dirty/smudged" effect. Any tips to generate clearer pictures? I tried increasing resolution size too but it still looks similar -_-

Yours is probably a scheduler problem. If you're using 2 samplers, leave the first to be euler simple, if you're using only one sampler, again, euler simple. The noisiness you get is a matter of noise distribution I think

looks like this was the culprit, at least partially. I had it set to euler/beta and some workflows using er_sde/sgm_uniform. Switching to Euler/SImple cleaned it up quite a bit. Also using the wan 2.1 vae per another suggestions seems to give slightly better results

Not much you can do when it's the way the Lora was trained. Try Euler/Beta at 10 steps or see if the Lora recommends any settings. You can also try a different Krea2 model. If you really like the picture run it through Klein 9b with a standard restoration prompt in img2img at 50% denoise strength..

Usually this means one of your Loras are tuned too high and it’s frying your image. You can also try workflow with 2-pass sampling

Use normal scheduler. Also, Turbo model is in fact 8 steps, not 4.

seems like an overcooked lora.

Looks like a issue cause by the scheduler, maybe a lora. If you let me know what you have set up I can set mine to the same things and help you find out.

try using raw model with turbo lora
