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. In the  The example shown , both U Vignette and V Vignette are checked. The example shown here uses a VRaySoftBox texture on a V-Ray light with both a radial vignette gradient and frame gradient turned on.

Parameters

...




Base Color – Control Controls the color of the texture. Enabling the checkbox on the right, enables the use of maps.

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 overal 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 – A multiplier for the brightness – Controls the strength of the hot/dark spot effect.

Hot Spot (Add) Color is added to the texture, adding brightness and creating a hot spot.Hot Adds more of the Base Color in the center area of the VRaySoftBox map. The amount added corresponds to the Multiplier value.

Dark Spot (Subtract) – Color is subtracted from the texture, removing brightness and creating a dark spot – Subtracts some of the Base Color in the center area of the VRaySoftBox map. The amount subtracted corresponds to the Multiplier value.

Tint Color – When enabled, allows control of enabled from the checkbox on the right, modifies the color of the hot spot.

Strength – A multiplier that controls how strong the effect of the Tint Color parameter is.

...

Softness – Controls the rate at which the hot spot fades out.

 

Gradients and Frame

V/U/Radial Vignette

The Gradients and Frame options allow you to blend gradient textures on top of the VRaySoftbox texture. You can add a gradient vignetting 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.

 

, and also radially.

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.

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 the speed of the noise procedural animation.

Fractal – Enables fractal noise.

Levels – Sets the levels for the fractal function.
