Welcome to the fascinating world of MatForger, a powerful generative diffusion model that helps designers create amazing Physically Based Rendering (PBR) materials! Whether you’re a designer, artist, or developer, this guide will walk you through the steps to effectively utilize MatForger to enhance your projects.

Model Overview

MatForger is designed to generate high-quality textures and materials by employing a unique noise rolling technique. It takes inspiration from the MatFuse model and utilizes the extensive MatSynth dataset for training. This model produces multiple texture maps, including basecolor, normal, height, roughness, and metallic maps, catering to diverse design needs.

Features of MatForger

• High-Quality PBR Material Generation: Create detailed and realistic materials.
• Tileable Textures: Generates tileable materials using the noise rolling method.
• Versatile Outputs: Produces a variety of texture maps for complex designs.
• Text and Image Conditioning: Allows material generation through either text prompts or image inputs.

How to Use MatForger

Before you dive in, ensure you have the necessary libraries, especially the diffusers library. Here’s a step-by-step guide on how to set up and use the MatForger model:

import torch
from PIL import Image
from diffusers import DiffusionPipeline

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
pipe = DiffusionPipeline.from_pretrained(
    "gvecchio/MatForger",
    trust_remote_code=True,
)
pipe.enable_vae_tiling()
pipe.enable_freeu(s1=0.9, s2=0.2, b1=1.1, b2=1.2)
pipe.to(device)

# Model prompting with image
prompt = Image.open("bricks.png")
image = pipe(
    prompt,
    guidance_scale=6.0,
    height=512,
    width=512,
    tileable=True,
    patched=False,
    num_inference_steps=25,
).images[0]

# Model prompting with text
prompt = "terracotta brick wall"
image = pipe(
    prompt,
    guidance_scale=6.0,
    height=512,
    width=512,
    tileable=True,
    patched=False,
    num_inference_steps=25,
).images[0]

# Get maps from prediction
basecolor = image.basecolor
normal = image.normal
height = image.height
roughness = image.roughness
metallic = image.metallic

Understanding the Code: An Analogy

Think of using MatForger as cooking a special dish. First, you gather your ingredients (install necessary libraries). Then, you choose a base recipe (load the model with from_pretrained). Next, you prepare your cooking environment (setting the device to either GPU or CPU). After that, you combine your ingredients according to the recipe – in this case, feeding either an image or text prompt to the model to generate your desired texture material. Finally, once everything is cooked to perfection, you can plate it (get various texture maps for use in your project).

Troubleshooting

Encountering issues while working with MatForger? Here are some common troubleshooting ideas:

• Quality Issues: If the generated materials don’t meet your expectations, be patient, and keep experimenting with different prompts. The model was trained on diverse data, but it may struggle with materials that deviate too much from its training distribution.
• Resolution Concerns: The model generates high-resolution materials through latent patching, but it works best at the original 256×256 resolution. Artifacts might appear at higher resolutions, so adjust your expectations accordingly.
• Various Errors: If you experience any unexpected errors, ensure your library versions are up to date and that you have the proper dependencies installed.
