FCRVSELECT

Layer Fog

 

The FcrvSelect->Layer Fog command in the Motion module displays the function curves of animated parameters related to the Layer Fog effect. For information on Layer Fog parameters, see the Atmosphere->Layer Fog command.

For more information on all tasks related to editing function curves, see the Editing Function Curves section of the Animating User's Guide.

 

Procedure

Choose the FcrvSelect->Layer Fog command and the desired subcommand.

The Fcurve window and the specified function curve(s) appear.

 

All

Displays all Layer Fog function curves.

Starting Distance

Displays the function curve for distance, in grid units, from the camera at which the Layer Fog is activated.

 

Note:

The Fog effect is "distance attenuated" so that objects near the starting distance are less affected by the Layer Fog effect than objects that are farther away.

Ending Distance

Displays the function curve for the distance, in grid units, from the camera at which the Layer Fog reaches full density and remains at full density from this point to infinity.

Colour

Displays the function curve for the colour of the Layer Fog. The colour values range from 0 to 1.

Density

Displays the function curve for the density of the Layer Fog. The values range from 0 to 1, with 0 as transparent and 1 as opaque.

Base

Displays the function curve for the starting distance of the Layer Fog, in grid units, from the xz plane. For example, setting the base at 0 activates the effect directly on the xz plane. Setting the base at -2 activates the Layer Fog at 2 units below the xz plane.

Thickness

Displays the function curve for the Layer Fog distance from the Base setting in the y plane. Thickness is also measured in grid units. For example, setting the thickness at 6 deactivates the Layer Fog at 6 units from the specified Base setting.

 

Note:

The Layer Fog effect is also attenuated according to its height, appearing the most dense at the midway point between the Base and Thickness settings, and gradually weakening toward its edges.
