We have released a new open sourced Minecraft Skin Generator XL model based on Stable Diffusion XL. It offers many improvements over the original model, including support for the transparency layer.
The model was fine-tuned on the dataset for 13,000 steps using the 'train_text_to_image.py' script provided with the diffusers library. A checkpoint has been included in the 'checkpoint' directory.
Some postprocessing is required to import and use the generated skins in Minecraft.
