Default guidance
| Code Block |
|---|
The pipeline uses the Euler Discrete Scheduler by default. We recommend using this scheduler with guidance scale=5.0 and num_inference_steps=50.
The pipeline also supports the EDMDPM Solver Multistep Scheduler. guidance scale=5.0 and num_inference_steps=25 is a good default for this scheduler. |

Is there way to draw legs correct?
| Info | ||
|---|---|---|

Use recommended by model creators CFG and STEPS (actually this answer is valid for all models). If SD.Next default values (20/6) gives bad result, you need to check hugging face and/or github of the model to find recommended values. For Kolors STEPS 50. CFG 5.0 as a starting point. |
