1. Introduction
- Importance of Realistic Materials: How PBR (Physically Based Rendering) enhances immersion in 3D scenes.
- Examples of Use: List use cases for realistic material workflows, such as architectural visualizations and interactive 3D product showcases.
2. Creating PBR Materials in Blender
- PBR Basics:
- Explain the concepts of metallic, roughness, and ambient occlusion maps.
- Steps to Set Up PBR in Blender:
- Setting up materials using Blender’s Principled BSDF shader.
- Assigning texture maps and configuring them for export.
- Texture Baking: How to bake textures for optimized web use and ensure minimal lighting artifacts.
3. Exporting Textures and Materials
- Exporting PBR Maps:
- Guidance on exporting diffuse, normal, roughness, and ambient occlusion maps.
- Export Settings: Recommended settings for different file formats and texture sizes.
- HDRI Lighting for Scene Realism: Using HDR images to create realistic reflections and environment lighting.
4. Implementing Lighting and Materials in Three.js
- Setting Up Lights:
- Tips on using directional, ambient, and point lights in Three.js for various effects.
- Integrating HDRI lighting for realistic reflections.
- Applying PBR Textures in Three.js: Converting Blender textures to MeshStandardMaterial or MeshPhysicalMaterial in Three.js.
5. Enhancing Scene Quality with Post-processing Effects
- Bloom and Glow Effects: How to add subtle bloom for metallic or emissive materials.
- Adding Depth of Field and Vignette: Enhancing realism with three.js post-processing libraries.
