This page contains information about the V-Ray Softbox Texture.

 


Overview

...

V-Ray Softbox is a procedural texture that can be used with a V-Ray Light to simulate the illumination coming from a Soft Box light source.

The example shown here shows the shader ball with a reflective material lit by an environment light with a V-Ray Softbox Texture applied.

Use Base Texture – When enabled, the Base Texture is used instead of the Base Color.

Base Texture – Specifies a texture to use as a base.

Base Color – Specifies a color to use as a base.

Base Multiplier – A multiplier for the brightness of the texture.

Base Gamma – A gamma correction that is applied to the texture.

Use Base Tint – When enabled, the color in the Base Texture parameter is multiplied by the Base Tint Color parameter.

Tint Color – Specifies a color to tint the light.

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

Use Frame Tint – Enables the frame tint.

Tint Color – Specifies a color to tint the frame.

Tint Strength – A multiplier that controls how strong of an effect the Tint Color has.

Enable Frame Noise – Enables frame noise.

Noise Amount – Controls the amount of effect the Noise has on the gradients.

Noise Size – Specifies the scale of the noise function.

Noise Phase – Controls the speed of the noise procedural animation.

Fractal Noise – When enabled, generates a fractal noise pattern.

Fractal Levels – When Fractal Noise is enabled, this controls the number of fractal iterations.

Spots

Section

Enable – Enables or disables the hot/dark spot.

Spots Mode – Specifies how the hot/dark spot is applied:

Hot Spot – Color is added to the texture, adding brightness and creating a hot spot. See the Hot Spot vs Dark Spot example below.
Dark Spot – Color is subtracted from the texture, removing brightness and creating a dark spot. See the Hot Spot vs Dark Spot example below.

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

Inner Radius – Specifies the inner radius where the hot spot begins to fade out as a fraction of the texture size.

Outer Radius – Specifies the outer radius where the hot spot ends as a fraction of the texture size.

Spots Multiplier – A multiplier for the brightness of the hot/dark spot.

U/V Offset – Controls the position of the spots along the U or V axis.

U/V Tiling – When enabled, controls the tiling of the spots along the U or V axis.

Spots Tint On – Enables the tint color for the spots.

Spots Tint Color – When enabled, controls the color of the hot spot.

Spots Tint Strength – A multiplier that controls how strong the strength of the Tint Color parameter.

Gradients

...

The Gradients options allow the user to blend gradient textures on top of the V-Ray Softbox texture. You can add a gradient in the U and V direction and place a frame - which is a gradient in both directions.

Example: Hot Spot vs Dark Spot

...


This example shows the difference between Hot Spot and Dark Spot modes. The Base Color is grey and the Tint Color is white. The Multiplier is set to 0.1.
