User Manual

Inspector
Controls Tab
The Controls tab includes all the parameters you use to decide how the Fog looks and projects
onto the geometry in the scene.
Enable
Use this checkbox to enable or disable parts of the node from processing. This is not the same
as the red switch in the upper-left corner of the inspector. The red switch disables the tool
altogether and passes the image on without any modification. The Enable checkbox is limited
to the effect part of the tool. Other parts like scripts in the Settings tab still processes as normal.
Show Fog in View
By default, the fog created by this node is visible only when the scene is viewed using a camera
node. When this checkbox is enabled, the fog becomes visible in the scene from all
points of view.
Color
This control can be used to set the color of the fog. The color is also multiplied by the density
texture image, if one is connected to the green input on the node.
Radial
By default, the fog is created based on the perpendicular distance to a plane (parallel with the
near plane) passing through the eye point. When the Radial option is checked, the radial
distance to the eye point is used instead of the perpendicular distance. The problem with
perpendicular distance fog is that when you move the camera about, as objects on the left or
right side of the frustum move into the center, they become less fogged although they remain
the same distance from the eye. Radial fog fixes this. Radial fog is not always desirable,
however. For example, if you are fogging an object close to the camera, like an image plane,
the center of the image plane could be unfogged while the edges could be fully fogged.
