This model can handle 2D, 2.5D, and 3D tasks. Although it's not perfect and might take a few tries to get the desired result, just keep experimenting with your prompts, and eventually, you will achieve what you want.
Best settings:
Sampling Method: Euler A, DPM++ 3M SDE Karras - you can mess around with this
Sampling Steps: 20 ~ 60 depending on your sampling method
Hires. fix: Enabled
Hires Steps: 15 ~ 30
Upscaler: 4x-AnimeSharp - You can test others since this is the only one I ever use.
Denoise Strength: 0.4
Upscale by: Preferably x2
CFG Scale: 6 ~ 9.5
Clip Skip: 2
Important:
Positive prompt must contain: score_9,score_8_up,score_7_up,
Negative prompt can be empty but preferably contain the default pony negatives.
Use "3d" in Negative prompt to generate 2d images.
I use Forge as my main UI because it has so many optimizations for running XL/Pony models on lower end GPU's despite me having a RTX 4090, generations are alot smoother. I'm not sure how this model performs on other UI's.
I haven't done much testing. If there is anything amiss, please let me know. Feedback is always appreciated :). This model excels at portraits.
Post results and, most importantly, have fun!
