To begin with, English is not my mother tongue, so I apologize in advance if there is any mistake.
I think this checkpoint can be unstable sometimes.
The images (character faces) I posted with this model have been inpainted at least one time.
The images are use multiples embeddings in the negative prompts so may be different if you don't have these embeddings.
Options i used:
Sampling method: DPM++ 2M SDE Karras
Sampling steps: 30
Upscaler: ScuNET PSNR
Hires steps: 20
Denoising strengh: 0.51
Please, don't use restore face.
Please, please, experiment and show me what my checkpoint is capable of !
