This page provides information on the Light Softbox Map.
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. The example shown here uses a VRaySoftBox texture on a V-Ray light.
Parameters
Base Color – 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 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.
Hot Spot/Dark Spot
On – Enables or disables the hot/dark spot.
Multiplier – 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.
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.
Tint Color – When 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.
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.
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.
Gradients and Frame
V/U/Radial Vignette
The Gradients 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 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.
