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. The example shown here uses a VRaySoftBox texture on a V-Ray light.
Base Color – Controls the color of the texture. Enabling the checkbox on the right, enables the use of maps.
Tint Color – When enabled, multiplies the color in the Base Color parameter is multiplied parameter by the the Tint Color parameterparameter.
Strength – A multiplier that controls how strong the effect of the Tint Color parameter is.
Processing
Multiplier – A – A multiplier for the overall VRaySoftBox texture. It acts similar to changing the multiplier of the VRayLight that uses this texture instead.
Gamma – A gamma correction that is going to be applied to the texture.

On – Enables or disables the hot/dark spot.
Multiplier – Controls – Controls the strength of the hot/dark spot effect.
Hot Spot (Add) – Adds more of the Base Color in the center area of the VRaySoftBox map. The amount added corresponds to the Multiplier value. See theHot Spot vs Dark Spot examplebelow.
Dark Spot (Subtract) – Subtracts some of the Base Color in the center area of the VRaySoftBox map. The amount subtracted corresponds to the Multiplier value. See theHot Spot vs Dark Spot examplebelow.
Tint Color – When enabled from enabled from the checkbox on the right, modifies the color of the 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 enabled, the options control the tiling of the texture along the U or V axis. See theTiling and Outer Radius examplebelow.
Fading Options
These options control how the hot/dark spot fades out into the base color.
Outer Radius – The outer radius where the hot spot ends as a fraction of the texture size. See theTiling and Outer Radius examplebelow.
Inner Radius – The inner radius where the hot spot begins to fade out as a fraction of the texture size.
Softness – Controls the rate at which the hot spot fades out.

V/U/Radial Vignette
The Gradients options allow you to blend gradient textures on top of the VRaySoftbox texture. You You can add a gradient vignetting in the U and V direction, and also radially. See theV/U/Radial Vignette examplebelow.
On – Enables the Vignette.
Flip – When enabled, the direction of the Vignette is flipped.
Gradient swatch –Use double click on the gradient swatch to add new color mark to it or refine the current mark. A set of self-explanatory options is available from the context menu.
Frame
The Frame options multiply the VRaySoftbox texture with a square shape gradient defined with the gradient swatch. See theFrame examplebelow.
On – Enables the Frame.
Flip – When enabled, the direction of the Frame is flipped.
Gradient swatch –Use double click on the gradient swatch to add new color mark to it or refine the current mark. A set of self-explanatory options is available from the context menu.
Tint Color – When enabled from the checkbox on the right, modifies the color of the gradient.
Strength – A multiplier that controls how strong the effect of the Tint Color parameter is.
Noise
Adds Noise to the Frame gradient.
Amount – Controls the amount of effect the Noise has on the gradients.
Size – Changes the scale of the noise function.
Phase – Controls – Controls the speed of the noise procedural animation.
Fractal – Enables fractal noise.
Levels – Sets the levels for the fractal function.
