billboards_impostor_base
A billboards_impostor_base material is used for impostors. It can be used for project optimization, when Cluster object will be replaced with ObjectBillboards.
States
In this tab you can set available settings and options:
Passes
Deferred - deferred rendering pass.
Options
Shadow shafts - simulates visible volumetric shadows, arising when a bright world light source is partially obscured by the object.
Textures
In this tab you can choose textures for billboards:

Material editor, Textures tab.

Base
Base textures are available:
Diffuse
Diffuse - diffuse texture. To create a diffuse texture for impostor, use Grabber tool.
Normal
Normal - base material normal texture. To create a normal texture for impostor, use Grabber tool.
Parameters
This tab represents parameters available for the material. All of the parameters have set default values, which can be replaced by your own ones. Availability of some parameters can depend on the set States tab values.

Transformation Parameters
Shading Parameters
Shading parameters:
Diffuse
Diffuse - Diffuse defines the base color of the surface.
Specular
Specular - Specular is a color picker to choose the auxiliary specular color for the specular texture. It can be used for specifying different specular colors for one texture or modifying the texture color on the spot. The specular color of the texture and this color will be blended.
Gloss Scale
Gloss scale - Gloss is a coefficient modifying the size of the highlight (Phong shading). Low values imitate wider highlights, typically appropriate to create diffuse reflection from mat surfaces. High values imitate pinpoint highlights, typically appropriate to create uniform reflection of light rays from glossy surfaces.
Normal Scale
Normal scale - Normal is a coefficient to scale the intensity of the normals (provided by a normal map). The higher the value, the higher the normal texture effect is.
Material Mask
Material mask - a decal bit-mask. If the material mask of the decal material matches the surface material, the decal will be projected.
