Applying Materials

Assigning materials to objects

Diffuse shaders

Using the Ramp Shader options

Ramps are basically a gradation of both color and transparency that can really transform the way that your materals look.

Additional shading options

Adding Textures

Adding a simple texture

Using bitmaps

Image or Movie Type

Image Mapping -> UV

UV Editing:

Please notice that a material can have multiple textures

Mapping textures in the UV Editor

Mesh menu -> Edges -> Mark Seam

Mesh menu -> UV Unwrap -> Unwrap:

Using UV projections

Function ShortCut Keys
Move projection Island mode, right click

Or Press G
Scale projection S

UV mapping a character

Practise

Projected mapping is view dependent

Fine-tuning UV mapping

Creating Bump and Normal maps

Texture -> Infulence -> Geometry

With bump mapping, just remember that the light colors are what’s creating the bumps. Dark colors create no bumps.

Displacement mapping

Texture -> Infulence -> Displace

Bump mapping is a surface effect; It does not change the underlying geomerty. Displacement mapping, however, does, although you do need enough geometry to displace. With Subdivision surfaces Modifier’s help, we can easily add more geometry without too much overload.

Using the node editor

Allow us to connect multiple textures together into a network of nodes that create more complex textures.

Working with Light

Adding lamps to a scene

Fine-tuning ray-trace shadows

Ray Shadow

Using spot lamps

Fine-tuning buffer shadows

Buffer shadows are based on a bitmap, which means they render faster, particularly for soft shadows.

Using Hemi lamps

No position for source, just control the direction

Working with Area lamps

From a specific region, rather than a point or a source.

Creating sky and ambient light

World panel

Adding background images

Texture -> Image -> Influence

Creating sunlight

Basically works the same as the Hemi lamp, in that it is directional and not positional. On of differences between them, the Sun lamp can do shadows.

Ambient occlusion

环境光遮蔽

Ambient occlusion creates an overall ambient lighting, and we have two forms: we have ambient occlusion, which is just a simple color or if we want to have more complex lighting, w can use Environment Lighting.
