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.
Dark Spot – Color is subtracted from the texture, removing brightness and creating a dark spot.
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.

Color Tweaks
Mult – Specifies a strength multiplier for the texture color.
Offset – Color corrects the texture by adding the the RGB color values specified here to the RGB color values in the texture.
Invert – When enabled, inverts the resulting texture color.
Alpha Tweaks
Source – Specifies where the alpha channel is drawn from.
...
Mult – Specifies a multiplier for the texture alpha.
Offset – Specifies an additional offset for the texture alpha.
Invert – When enabled and Invert from Color Tweaks is also enabled, the resulting texture alpha will be inverted as well.
Placement
Placement Type – Specifies the way the valid portion of the texture is applied.
Full – Uses the full valid portion of the texture.
Crop – Allows the user to specify a section of the texture using the parameters below.
Place – Allows the user to specify a section of the texture and how to place it using the parameters below.
U – Specifies the U coordinate of the valid texture sector.
V – Sppecifies the V coordinate of the valid texture sector.
W – Specifies the width of the valid texture sector.
H – Specifies the height of the valid texture sector.
Jitter – Controls the amount of random placement variation.
Tile U – Enables horizontal tiling.
Tile V – Enables vertical tiling.
UV Noise
Enabled – Enables noise for the texture.
Amount – Specifies the amount of noise to add to the texture.
Levels – Specifies the amount of noise iterations.
Size – Controls the scale of the noise.
Animated – Enables the noise to be animated.
Phase – Controls the noise phase.
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.
