Hi all, amazing thread. I just got here but I've been playing with sd for a few weeks. Trying out Nano and MrFox's recommendations on the neverendingdreamNED_bakedVAE model:
beautiful, masterpiece, best quality, hiqcgbody, anime, 1girl, sam yang, halter cut dress, mascara, flirty, blunt bangs, portrait shot, looking at viewer, glossy lipstick, nightclub, intricate details,<lora:hipoly3DModelLora_v10:0.5> <lora:samdoesartsSamYang_normal:0.5>
Negative prompt: (painting by bad-artist:0.9), easynegative, (worst quality, low quality:1.4), watermark, text, error, blurry, jpeg artifacts, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, artist name, bad anatomy, deformed iris.
Size: 448x640, Seed: 3686603218, Steps: 28, Sampler: DPM++ SDE Karras, CFG scale: 7, Clip skip: 2, Model hash: d8722b4a4d, Hires steps: 20, Hires upscale: 1.75, Hires upscaler: Latent (bicubic antialiased), Denoising strength: 0.55
Works perfectly fine for me if I use a 512x512 resolution, but I get some pretty strange facial deformations when I try with 448x640 hires by 1.75x. The NON-hires, non-upscale (native 448x640) via txt2img is fine, but even if I remove the LORAs, my faces are always deformed by the txt2img+SD upscale at a non 1:1 aspect ratio. I've tried with a lower (0.45) denoise, and it's still messed up.
This seems to be a problem specifically with the hires fix.
Just using img2img upscale alone is inferior, and removes all the skin textures, so that's no use...
TLDR:
512x512 hires fix upscales via txt2img looks great, works fine.
Non 1:1 ratio hires fix upscale via txt2img ... sucks.
Does anyone have any suggestions? I wonder if it's an Apple Silicon issue? I've googled and reddited to no avail.
