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.
