whenever I try to generate a standalone planet, I get a planet next to a planet.
How do I get an Isolated planet in space? |

From what I understand (and I might be misunderstanding things), a flaw in how Stable Diffusion was trained makes it unable to generate pictures that are too dark. And all that space around your planet adds too much darkness, so SD feels compelled to fill that space with something brighter, like another planet. Using Img2Img you can "trick" Stable Diffusion, by adding a lot of white pixels that bring the average brightness of the image up.

I guess I will have to wait for SDXL, I hear they solved the darkness problem but unfortunately they won't have controlnet on day 1. Is there a way to use controlnet and img2img at the same time in comfyUI? It seems that the workflow only allows one. |

You can do anything you want. The workflow configuration of ComfyUI is very flexible. https://www.youtube.com/watch?v=X5Jz_C--rs0 And if you want to completely clear the area around the planet, I would recommend using a mask. If you want to fill something else, you can create the planet using a mask on the controlnet, and then inverse the mask to fill the remaining parts. This way, you can set up a workflow to accomplish the task. |

Ok, so what initially took me about 30min to do - turned into 4hrs of Design to try to make your life easier - and anyone else who wants to use this workflow. Basically it will create a planet from a simple sketch (@ninjasaid2k I used your example sketch above) - you "can" technically use any sketch and it'll do something magic with it. ;) Hope this helps..! updated -> Lonely Planet From Sketch.zip

I updated the workflow (in zip file) - I needed to tweak something updated -> Lonely Planet From Sketch.zip |

Made Another change - added "Real" seed feedback box - so you know exactly what seed the image is on (because ComfyUI is rubbish at telling you the actual seed being used) updated -> Lonely Planet From Sketch.zip
