Undertale [XL, Pony, Flux] LoRA

Undertale LORAs for SDXL/Flux

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:

• Used around 800 images in total, with some later additions

• Can influence style quite significantly (mostly 3.0 models)

Flux LoRA:

• Currently being trained using split mode and fp8 version of dev model

• Quality uncertain at this time

• Uses smaller dataset of 558 images and less repeats, Florence2/JoyCaption captioning + corrections by me

• Possibly would retrain at some point

Characters: Asriel, Chara, Frisk, Muffet, Sans, Papyrus, Undyne, Gaster, Toriel, Mettaton, Grillby, Alphys, Flowey, Asgore, Napstablook

Note: 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:

• Trigger words: character_(undertale)

  • Some characters work well with trigger words alone

  • Others require additional prompting

• Flux: Natural language prompting

• SDXL: Booru tagging

• The _(undertale) part isn't strictly necessary

Model-Specific Notes:

1. Flux:

   • Use guidance of 3.5 or higher for better character likeness

   • Higher guidance may increase stylistic differences between images

2. Animagine 3.1:

   • Model 1.2 surpasses previous versions in flexibility and capabilities

   • Stylistic differences between versions are subjective

   • Personal preference: Model 1.2.5 for style, but has biases due to initial overfitting

3. Base XL:

   • Second model trained on base model for broader compatibility, as a substitute when other models don't work

   • Intended for use with any model, but struggles with anime models

   • Examples not limited to Animagine v3

   • Currently not fully accurate, performance varies by model

4. PonyXL:

   • Trained on civitai

   • Can produce good outputs

   • Missed some character features

Note: There may be stylistic inconsistencies, so it's better to specify your preferences when generating images.
