If You Like This Model, Give It a ❤️
This LoRA model is trained on sprite images from the popular games Jump Superstars and Jump Ultimate Stars. These games feature stunning pixel art graphics and showcase characters from Weekly Shonen Jump.
Quick Tips
No Trigger Word Required: LoRA operates seamlessly without the need for a trigger word.
Recommended Resolution: Our model is trained on 96x96 resolution images, which are then upscaled to 768x768 resolution. For the best results, we recommend setting your image resolution to 768x768 and then downscaling it by 8 times to 96x96. You can use various image editing programs, but we highly recommend using the plug-in for post-processing. (Plugin: https://github.com/mrreplicart/sd-webui-pixelart) Other resolutions, such as 512x768 and 1024x1024, may also work, but make sure they are divisible by 8 for the best pixel art results.
Class Tags: LoRA is trained with character name tags (without spaces), including names like
goku,naruto,luffy,lightyagami,jotarokujo, andKenshin. Additionally, the model is trained with manga name tags (without spaces), such asnarutoshippuden,onepiece,yugioh,shamanking,saintseiya,princeoftennis, andruronikenshin. To explore all the character and manga names available, please visit the sprite-database website (Jump Superstars, Jump Ultimate Stars).LoRA Scale: If you wish to generate characters from the Jump games, we recommend using a LoRA scale of 0.9-1.0. For characters already known by the base model, a scale of 0.6-0.8 is recommended. This model can also combine LoRA to create unique characters not known to the base model. In such cases, please use a LoRA scale of about 0.6-0.8 and ensure a sufficient number of sampling steps.
Enjoy creating your sprite art with LoRA!

Verry nice 96x96 pixel perfect lora model ! what is the trick to get this when i train my lora ?
I've been trying for several weeks to train a 128x128 pixel perfect with up to 5000 sprite from arcade game in 128x128 upscaled to 512x512 but i not get this sharp result....
can you give me your settings to configure kohya ?
I'm not really sure too. One trick that I used is always 8x upscale our sprites, for example 64 -> 512 or 92 ->768. I believe 8x is the same number that vae upscale our latent to images so 8x is a magic number (I believe). However, seem like it is not all, my lora training also fail to give perfect pixel many time even upscale 8x already so finger cross. For config, I usually start with the preset sd15_LoraOptiSet and adjust Network Rank and Epoch depend on task.
@titansteng Thanks for the tip ! i will try to upscal my set to 1024 (8*128)....
@yodad2r2233 One person here overlaid a grid on the pixel art. It did surprisingly well at making sure pixels are where they're supposed to be. Everything lined up perfectly. I'm currently doing my own tests with arcade game sprites (CPS2 Capcom).
