volume_shaft_base
A volume_shaft_base material is used to create beams of light falling into a dark room through windows or any other openings. In case colored glass is used for windows, beams also will be colored.
This material is applied only to Volume boxes.
States
In the States tab you can set rendering passes and available options. Enabling some of the states activates additional textures and parameters in the Textures and Parameters tabs respectively.
For this material the states contain only Options field.
Possible values for a Samples option:
| GUI name | XML name | Description |
|---|---|---|
| 16 | 16 | A density texture is sampled to render a volume box 16 times. |
| 32 | 32 | A density texture is sampled to render a volume box 32 times. |
| 64 | 64 | A density texture is sampled to render a volume box 64 times. |
| 128 | 128 | A density texture is sampled to render a volume box 128 times. |
| 256 | 256 | A density texture is sampled to render a volume box 256 times. |
All the states can be set to default ones - click a
Set to parent button near the state (if the state is different from the default one, its field will be highlighted with green).
The states available for this kind of materials are listed below.

Parameters
In the Parameters tab you can set or modify base and additional parameters.
Parameters of different types are set in different ways:
- slider - the value can be set either by smoothly moving the slider of the scroll box or manually in the box near the parameter (if required, the value bigger than maximum one for the slider can be set)
- color - the color can be chosen in the dialog window, activated after double clicking the color field
All the parameters can be set to default ones - click a
Set to parent button near the parameter (if the parameter is different from the default one, its field will be highlighted with green).

Shading Parameters
Shading parameters are modified in the Shading field of the Parameters tab.
| GUI name | XML name | Type | Description |
|---|---|---|---|
| Diffuse | diffuse_color | color |
A color picker specifying diffuse color. |
Density Parameters
Density parameters are modified in the Density field of the Parameters tab.
| GUI name | XML name | Type | Description |
|---|---|---|---|
| Multiplier | volume_density | slider | A coefficient to scale the density of the cloud. The density value multiplies the value of the G channel of the density texture. By the minimum value of 0, the cloud is not rendered at all. The higher the value, the bigger and darker cloud is (if a default texture is used). |
