JRPG Pixel Art Background Generator

Model Description

JRPG Background Generator is a Diffusion Model trained from scratch to generate pixel art backgrounds in the style of classic JRPG games (Final Fantasy, Chrono Trigger, Secret of Mana).

The model uses a UNet2D architecture with DDPM (Denoising Diffusion Probabilistic Models) scheduler to generate 128x128 pixel art landscapes.

Model Details

Model Type: Diffusion Model (DDPM)
Architecture: UNet2D with Attention Blocks
Resolution: 128x128 pixels
Training Epochs: 600
Training Time: ~200 hours on NVIDIA GPU
Framework: PyTorch + Hugging Face Diffusers
Parameters: ~45M

Supported Styles

The model can generate various scene types:

🏜️ Desert ruins and ancient temples
🏰 Castles and fortresses
🏔️ Canyons and mountain passes
☁️ Floating islands
🌅 Sunset/sunrise landscapes
🌊 Coastal scenes
- and lot of more

Intended Use

Primary Use Cases

Indie Game Development: Generate background assets for retro-style RPG games
Concept Art: Quick ideation for game environments
NFT Collections: Create unique pixel art landscape collections
Game Prototyping: Rapid background generation for mockups
AI Art Research: Study diffusion models on pixel art domain

Out-of-Scope Use

Photorealistic image generation
Character/sprite generation
High-resolution outputs (>256x256)
Real-time generation (inference takes ~30-60 seconds)

How to Use

Installation

pip install torch diffusers pillow matplotlib transformers

Quick Start

Kullanım

from diffusers import DDPMPipeline

pipe = DDPMPipeline.from_pretrained("ayhant/Pixel-Art-JRPG-Background-Generator")
image = pipe(batch_size=1, num_inference_steps=256).images[0]
image.save("background.png")

Training Details

Training Data

Dataset Size: Custom curated dataset of ~500 JRPG background images
Data Sources: Open Art, Final Fantasy series, Chrono Trigger, Secret of Mana, etc.
Preprocessing:
- Resized to 128x128
- Random horizontal flip augmentation
- Normalized to [-1, 1]

Training Hyperparameters

- Training epochs: 100
- Batch size: 32
- Learning rate: 1e-4
- Optimizer: Adam
- Scheduler: DDPM (512 timesteps)
- Loss function: MSE Loss
- GPU: NVIDIA (CUDA)

Training Procedure

for epoch in range(100):
    for batch in dataloader:
        # Random timestep
        timesteps = torch.randint(0, 512, (batch_size,))
        
        # Add noise
        noise = torch.randn_like(batch)
        noisy_images = scheduler.add_noise(batch, noise, timesteps)
        
        # Predict noise
        noise_pred = model(noisy_images, timesteps).sample
        
        # MSE loss
        loss = F.mse_loss(noise_pred, noise)
        
        # Backprop
        optimizer.zero_grad()
        loss.backward()
        optimizer.step()

Evaluation

Qualitative Results

The model successfully generates:

✅ Diverse scene compositions
✅ Appropriate color palettes (warm/cool contrasts)
✅ Volumetric lighting effects
✅ Multi-layered depth perception
✅ JRPG aesthetic consistency

Limitations

🔸 Limited to 128x128 resolution
🔸 Occasional artifacts in complex scenes
🔸 Inference time: ~10-20 seconds per image
🔸 Cannot generate characters or sprites
🔸 Style limited to training dataset
