The popular "Hotaru's LoRA series" (for SD1) is now available for SDXL! More will be released gradually on CivitAI (already available on HuggingFace). Using only prompts, it is difficult to render characters and backgrounds as dark while keeping only light sources bright (such as lamps, the moon, and stars). This LoRA enables to generate such images. This LoRA is compatible with Pony / Animagine / Illustrious based checkpoints, but Pony based checkpoints will make better results. Some checkpoints may have less compatibility. This LoRA is suitable for 2D-2.5D illustrations only and not suitable for photorealistic checkpoints. My "Breed" series checkpoints will make good outputs. Sample images are generated with "Breed" series listed on "Suggested Resources" section. SD1 version is also available. Usage It works simply by enabling the LoRA, so basically no additional prompts are necessary. But adding prompts such as darkness or dark sky to indicate darkness can lead to better results. If you want to make the character's eyes glow, add glowing eyes. The level of darkness can be adjusted by the LoRA weight. For a darker effect, increase the weight. The upper limit is around 2.0.
