Basics: Shaders/Materials.
Working with color particle : color, expression, expression shader, ...
Texture :
Which type Particle, we can use texture ?
Create textures on Adobe Photoshop.
Apply textures to particles.
Examples:
Create a spacecraft flying in the sky stars.

1.1.1) Shaders/Materials.
1.1) Shaders/Materials
Define an object’s substance.
Surface textures .
o How light is reflected.
Surrounding environment.
1.1.2) Basic attributes of materials.
1.1) Shaders/Materials
Color
o Change basic color.
o Apply a texture as a color map.
Transparency
o Change basic transparency.
o Apply a texture as a transparency map.
Shine
o Change the intensity and size of the specular highlights of an object.
o Apply a texture as a specularity map.
1.1.2) Materials Types
Anisotropic: This material has elliptical specula highlights.
Blinn: Provides soft circular highlights and is good for metallic surfaces.
Lambert: This material has no highlights and is useful for cloth and non-reflectivesurfaces.
Layered Shader: Combines several shaders into one single shading object.
Phong: Provides hard circular highlight and is good for glass surfaces.
Phong E: Similar to Phong, but optimised to render faster.
Shading Map: This material allows for colour changes to the rendering whichprovides cartoon shading.
Surface Shader: Provides a connection to a surface material attributes.
Used Background: Allows for adjustment and control of an objects shadows andreflections.
