[v3.1 is still in further testing. Updates regarding new findings will be updated in the "About this version" section]UrangDiffusion v3.1 (oo-raw-ng Diffusion) is the first UrangDiffusion version that utilize Animagine XL 4.0 as the base.The name “Urang” comes from Sundanese, meaning “We/Our/I.” The history behind the name is to make the model not only suitable for me but also for many people. Another reason is that I use many resources (training scripts, dataset collecting scripts, etc.) from other people. It’s unfair to claim this model as “my sole work.”<h2 id="standard-prompting-guidelines-hlzesdv89">Standard Prompting Guidelines</h2><ul><li>Prompting guide:<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/04b4aacf-0336-4fd5-a221-ea1e29dcf9b5/width=525/04b4aacf-0336-4fd5-a221-ea1e29dcf9b5.jpeg" /></li></ul><ul><li>Default negative prompt: <code>lowres, bad anatomy, bad hands, text, error, missing finger, extra digits, fewer digits, cropped, worst quality, low quality, low score, bad score, average score, signature, watermark, username, blurry</code></li><li>Default configuration: Euler a with around 25-30 steps, CFG 5-7, and ENSD set to 31337.

The base model is trained with only 10 epochs, which lead to the model being undertrained.

UrangDiffusion v3.1

Using huber loss for better training.Using random cropping for better image results.Added new characters from new series, updated undertrained characters, and add new characters from existing series.
