Study Notes
Materials
- Materials define the appearance of a mesh, including color, texture, and reflection.
- They are data blocks that can be assigned to multiple 3D objects.
- You can assign different materials to a single 3D object.
Displacement
- Displacement alters the shape of surfaces and volumes, making the mesh more detailed.
- Bump mapping is a virtual displacement that alters shading but not the mesh.
- It is the least accurate but most memory-efficient method.
- Displacement provides the most accurate and memory-intensive method, applying actual displacement to the mesh.
- Mixed displacement combines bump mapping and displacement to provide a balance of accuracy and memory usage.
Principled BSDF
- The default shader in Blender.
- It combines multiple layers into a single node.
- It is based on the Disney principled model and compatible with other software such as Pixar Renderman and Unreal Engine.
Principled Hair BSDF
- A dedicated shader for rendering hair and fur.
- It allows for random color and roughness in hair, making it more realistic.
Principled Volume
- Combines all volume shading components into one easy-to-use node.
Other BSDF Nodes
- Refraction BSDF adds glossy refraction for materials like water and glass.
- Specular BSDF focuses on specular reflections, useful for materials like metal.
- Subsurface Scattering BSDF simulates light scattering beneath the surface, for elements like skin or wax.
- Toon BSDF creates cartoon light effects for diffuse and glossy materials.
- Transparent BSDF creates true transparency with no refraction.
- Translucent BSDF adds a Lambertian diffuse transmission.
- Velvet BSDF adds reflections to materials like cloth.
Volume Shaders
- Volume Absorption BSDF controls light being absorbed as it passes through a volume to simulate the effect of materials like colored glass.
- Volume Scattering BSDF manages the scattering of light as it passes through a volume - often used for fog and smoke.
Texture
- Textures are flat images applied to 3D models to give color and detail.
- They are often used for 3D environments and objects.
- Textures affect the surface of an object, while the materials affect the object.
Types of Textures
- Procedural Textures are created using mathematical nodes and don't rely on image files.
- They are resolution independent and can be used to create realistic materials quickly.
- Bitmap Textures are produced using image files and require UV mapping.
- These textures can be in formats such as JPEG, PNG, and TGA.
