Standard Tab

Boundary Settings

Start Point: The Start Point is the point at which the FogPlus effect begins, measured from the camera eye point (in meters).
Saturation Point: The Saturation Point is the point of saturation, where the FogPlus effect is strongest (measured in meters from the camera eye point).
[Set] Button: Click the [Set] button and then click on the preview image to set the value to the clicked position. The image must be rendered with Keep Z checked.
Use Joint Checkbox: The FogPlus Controller joints will be used, with any applied animation settings, if this is checked.

Density Settings

Max Density Textbox and Slider: The level of the strongest FogPlus effect, reached at the Saturation point. 100% is completely opaque fog.
Use Joint Checkbox: The FogPlus Controller joints will be used, with any applied animation settings, if this is checked.
Curve Textbox and Slider: The FogPlus Curve value determines how fast the fog effect gets stronger.; The default value is 0.5, which describes a linear relationship between distance from the camera eye point and FogPlus strength.
A value smaller than 0.5 describes a relationship in which the FogPlus effect becomes dense quickly and then continues to grow in intensity more slowly until the Saturation point.
A value larger than 0.5 describes a relationship in which the FogPlus effect becomes dense slowly and then sharply increases in intensity close to the Saturation point.

The FogPlus Curve value is set to 0.5, 0.1, and 0.9 from top to bottom, with all other settings the same.

Vertical Tab

Boundary Settings

Location Pop-up Menu

The location at which the Vertical Fog effect begins.

Ground: Ground Fog gets more dense moving down the Y axis (towards the ground, or Bottom value).
Ceiling: Ceiling Fog gets more dense moving up the Y axis (towards the ceiling, or Top value).

Top Textbox

The Top value along the Y axis for Vertical Fog. This is the point at which Ceiling Fog is strongest. If Ceiling is selected in the Location pop-up menu and the camera eye point is above the Top value, no fog will be drawn.

Bottom

The Bottom value along the Y axis for Vertical Fog. This is the point at which Ground Fog is strongest.
If Ground is selected in the Location pop-up menu and the camera eye point is below the Bottom value, no fog will be drawn.

Use Joint Checkbox

The FogPlus Controller joints will be used, with any applied animation settings, if this is checked.

Density Settings

Max Density Textbox and Slider: The level of the strongest FogPlus effect, reached at the Saturation point. 100% is completely opaque fog.
Use Joint Checkbox: The FogPlus Controller joints will be used, with any applied animation settings, if this is checked.
Amount Textbox and Slider: The overall strength of Vertical Fog. Fog will not grow any stronger past the Saturation point.; This value is not an absolute value; it is relative to the FogPlus effect range determined by the Start Point and Saturation Point.

The FogPlus Amount is set to 200, 250 and 300 from top to bottom, using the same FogPlus range values.

Options Tab
