VRaySphereFade Parameters


 

 

 

Gizmos – Holds a list of the atmospheric gizmos that are going to be affected of the VRaySphereFade atmospheric.

Pick – Click to pick atmospheric gizmos from the scene to add them to the Gizmos list.

Remove – Removes the selected gizmo from the Gizmos list.

Falloff – Specifies a falloff radius to blend the content in the atmospheric gizmo with the background.

Empty color – Specifies the color for the background - everything outside the atmospheric gizmos.

Affect alpha – When enabled, V-Ray will render an alpha channel where everything outside the atmospheric gizmos will be transparent and the objects inside the gizmos will have their normal alpha.

 

Example - Relative falloff


The examples below all use a sphere gizmo with a radius of 16.0 aligned to the center of the bowl. This will provide the active area used by VRaySphereFade and has been added as an active gizmo in the VRaySphereFade parameters list. By changing the value of the Relative falloff the amount of fade can be adjusted. The fade effect takes place from the gizmo itself inwards, so the gizmo must contain that you wish to see.


The Sphere Gizmo has been aligned to the center of the bowl.
