# StableMaterials

**StableMaterials** is a diffusion-based model designed for generating photorealistic physical-based rendering (PBR) materials. This model integrates semi-supervised learning with Latent Diffusion Models (LDMs) to produce high-resolution, tileable material maps from text or image prompts. StableMaterials can infer both diffuse (Basecolor) and specular (Roughness, Metallic) properties, as well as the material mesostructure (Height, Normal). 🌟

</center>

### 🧩 Base Model 
The base model generates low-resolution (512x512) material maps using a compression VAE (Variational Autoencoder) followed by a latent diffusion process. The architecture is based on the MatFuse adaptation of the LDM paradigm, optimized for material map generation with a focus on diversity and high visual fidelity. 🖼️

### 🔑 Key Features
- **Semi-Supervised Learning**: The model is trained using both annotated and unannotated data, leveraging adversarial training to distill knowledge from large-scale pretrained image generation models. 📚
- **Knowledge Distillation**: Incorporates unannotated texture samples generated using the SDXL model into the training process, bridging the gap between different data distributions. 🌐
- **Latent Consistency**: Employs a latent consistency model to facilitate fast generation, reducing the inference steps required to produce high-quality outputs. ⚡
- **Feature Rolling**: Introduces a novel tileability technique by rolling feature maps for each convolutional and attention layer in the U-Net architecture. 🎢

## Intended Use

StableMaterials is designed for generating high-quality, realistic PBR materials for applications in computer graphics, such as video game development, architectural visualization, and digital content creation. The model supports both text and image-based prompting, allowing for versatile and intuitive material generation. 🕹️🏛️📸
