<h3 id="undertale-loras-for-sdxlflux-mqq5mgy00">Undertale LORAs for SDXL/Flux</h3>I've noticed a lack of Undertale LORAs for SDXL, so I've trained one on Animagine XL v3.x. It can work on some other models as well. I also trained a PonyXL and Base model version s and right now Flux LoRA in process.Training Data for SDXL:<ul><li>Used around 800 images in total, with some later additions</li><li>Can influence style quite significantly (mostly 3.0 models)</li></ul>Flux LoRA:<ul><li>Currently being trained using split mode and fp8 version of dev model</li><li>Quality uncertain at this time</li><li>Uses smaller dataset of 558 images and less repeats, Florence2/JoyCaption captioning + corrections by me</li><li>Possibly would retrain at some point</li></ul>Characters: Asriel, Chara, Frisk, Muffet, Sans, Papyrus, Undyne, Gaster, Toriel, Mettaton, Grillby, Alphys, Flowey, Asgore, NapstablookNote: Quality varies between characters. In version 1.0 of Animagine, avoid generating Asgore or Napstablook due to overfitting. Version 1.1 and onwards work better, but caution is still advised.Parameters:<ul><li>Trigger words: character_(undertale)<ul><li>Some characters work well with trigger words alone</li><li>Others require additional prompting</li></ul></li><li>Flux: Natural language prompting</li><li>SDXL: Booru tagging </li><li>The _(undertale) part isn't strictly necessary</li></ul>Model-Specific Notes:<ol><li>Flux:<ul><li>Use guidance of 3.5 or higher for better character likeness</li><li>Higher guidance may increase stylistic differences between images</li></ul></li><li>Animagine 3.1:<ul><li>Model 1.2 surpasses previous versions in flexibility and capabilities</li><li>Stylistic differences between versions are subjective</li><li>Personal preference: Model 1.2.5 for style, but has biases due to initial overfitting</li></ul></li><li>Base XL:<ul><li>Second model trained on base model for broader compatibility, as a substitute when other models don't work</li><li>Intended for use with any model, but struggles with anime models</li><li>Examples not limited to Animagine v3</li><li>Currently not fully accurate, performance varies by model</li></ul></li><li>PonyXL:<ul><li>Trained on civitai</li><li>Can produce good outputs</li><li>Missed some character features</li></ul></li></ol>Note: There may be stylistic inconsistencies, so it's better to specify your preferences when generating images.

Undertale [XL, Pony, Flux] LoRA

This is a mix between 1.2.5 and A31 versions. A31, while flexible, often gets something wrong about characters or less detailed, so the mix makes it to be something in-between. Influences the style closer to what 1.2.5 does. It's actually better with multiple characters than A31.
