VRaySoftBox
VRaySoftBox Overview
The VRaySoftbox is a procedural texture that can be used in a V-Ray Area Light to create the illumination coming from a Soft Box light source.
Base Parameters
Base Color - allows the user to control the color of the texture.
Tint Color - when enabled, the color in the Base Color parameter is multiplied by the Tint Color parameter.
Strength - a multiplier that controls how strong the effect of the Tint Color parameter is.
Processing
Multiplier - a multiplier for the brightness of the texture.
Gamma - a gamma correction that is going to be applied to the texture.
Hot Spot/Dark Spot
On - enables or disables the hot/dark spot.
Multiplier - a multiplier for the brightness of the hot/dark spot.
Hot Spot (Add) - color is added to the texture, adding brightness and creating a hot spot.
Hot Spot ( Subtract) - color is subtracted from the texture, removing brightness and creating a dark spot.
Tint Color - when enabled allows you to control the color of the hot spot.
Strength - a multiplier that controls how strong the effect of the Tint Color parameter is.
Tiling Options
U/V Offset - controls the position of the texture along the U or V axis.
U/V Tiling - when the check box is enabled, the options control the tiling of the texture along the U or V axis.
Fading Options
These options control how the hot/dark spot fades out into the base color.
Outer Radius - this is the outer radius where the hot spot ends as a fraction of the texture size.
Inner Radius - this is the inner radius where the hot spot begins to fade out as a fraction of the texture size.
Softness - this parameter controls the rate at which the hot spot fades out.
Gradients and Frame
The Gradients and Frame options allow you to blend gradient textures on top of the VRaySoftbox texture. You can add a gradient in the U and V direction and place a frame - which is a gradient in both directions. You can also add noise to the frame.
