Usage

Using with Diffusers

import torch
from diffusers import DiffusionPipeline

# Load base model
pipe = DiffusionPipeline.from_pretrained(
    "black-forest-labs/FLUX.2-klein-base-9B",
    torch_dtype=torch.bfloat16
)
pipe.to("cuda")

# Load LoRA
pipe.load_lora_weights("Mystic07/flux-lora-spritesheet", weight_name="gmsspritesheet1.safetensors")

# Generate
prompt = "gmsspritesheet, 4 direction sprite sheet, warrior character, walk cycle animation, pixel art"
image = pipe(
    prompt=prompt,
    num_inference_steps=30,
    guidance_scale=4.0,
    width=1024,
    height=1024
).images[0]

image.save("sprite_sheet.png")

Using with ComfyUI

1. Download gmsspritesheet1.safetensors
2. Place it in ComfyUI/models/loras/
3. Add a "Load LoRA" node in your workflow
4. Use trigger word gmsspritesheet in your prompt

Example Prompts

gmsspritesheet, 4 direction sprite sheet, warrior character, walk cycle animation, pixel art

gmsspritesheet, sprite sheet, mage character, spell casting animation, top-down view

gmsspritesheet, 4 direction sprite sheet, archer character, shooting bow, pixel art style

gmsspritesheet, character sprite sheet, knight in armor, idle and attack animations

gmsspritesheet, sprite sheet, rogue character, stealth movement, multiple poses

Recommended Settings

• Steps: 20-40 (30 recommended)
• Guidance Scale: 3.5-5.0 (4.0 recommended)
• Resolution: 1024x1024 or 768x768
• Sampler: Any (Euler, DPM++ work well)

Training Details

• Dataset: 18,706 LPC-style sprite sheet images
• Learning Rate: 1e-4
• Optimizer: AdamW
• Batch Size: 1
• Resolution: 1024x1024
• Training Time: ~3 hours on A100-40GB

Use Cases

• Game development sprite assets
• Character animation references
• Pixel art style generation
• Top-down RPG character sprites
• Walk cycles and action animations

Limitations

• Best results with pixel art and sprite sheet styles
• Optimized for character sprites (humanoid forms)
• May struggle with very complex multi-character scenes
• Works best with the trigger word gmsspritesheet
