**Front / Side Color** – Sets the extreme ends of the range of colors for the Falloff Map's gradient. The specific placement of these colors on the surface is determined by **Falloff Type** and **Falloff Direction**.

**Falloff Type** – Specifies the type of falloff:

**Towards/away** – Based on face normal directions. Faces with normals that point in the **Falloff Direction** generate the **Front Color** while those facing in the opposite direction (180 degrees off the falloff direction) generate the **Side Color**.   
 **Perpendicular/Parallel** – Based on face normal directions. Faces with normals that point in the **Falloff Direction** generate the **Front Color** while those facing in a perpendicular direction (90 degrees off the falloff direction) generate the **Side Color**.  
 **Fresnel** – Based on changes to the index of refraction (IOR) over the surface due to Fresnel calculations. Faces with normals that point in the **Falloff Direction** generate the **Front Color** and those facing in other directions generate varying colors depending on the IOR set by **Fresnel Index Of Reflection**.   
 **Distance blend** – Sets the falloff range based on distance from the camera, as specified by **Near Distance** and **Far Distance**. This option is useful for generating a Z-depth type of map when rendering a very large object such as terrain, where the Falloff Map can be used as a mask to dim distant details. *For more information, see the **[Distance Falloff Type example](#)** below.*

**Falloff Direction** – Specifies the falloff direction to be used by the **Falloff Type**. 

**Viewing Direction (Camera Z-Axis)** – Uses the camera viewing direction. This is the most common selection.  
 **viewX / viewY** –Uses one of the camera's other axes.  
 **Explicit direction** –Uses the direction specified by the **Explicit direction** parameter.  
 **local X** / **local** **Y** / **local** **Z** –Uses one of the object's local axes.  
 **worldX** / **world** **Y** / **world** **Z** –Uses one of the world axes.

 

### **Mode Specific Parameters**

**Explicit direction** – Specifies the direction for falloff when **Falloff Direction** is set to **Explicit direction**.

**Fresnel index Of reflection** – Defines the IOR (Index of Refraction)when **Falloff Type** is set to **Fresnel**.

**Near distance** – When **Falloff Type** is set to **Distance**, parts of the surface at this distance from the camera will receive the **Front Color**. *For more information, see the **[Distance Falloff Type example](#)** below.*

**Far distance** – When **Falloff Type** is set to **Distance**, parts of the surface at this distance from the camera will receive the **Side Color**. *For more information, see the **[Distance Falloff Type example](#)** below.*

**Extrapolate** – When enabled, the effect continues beyond the range set by **Near Distance** and **Far Distance**. Parts of the surface nearer than **Near Distance** receive the **Front Color**, while parts farther from the camera than **Far Distance** will receive the **Side Color**.

**Enable color map** – Turns on the **Remap Curves**.

**mix** – Controls the mix of the **Front color** and the **Side color**.

**red** – The intensity of the red channel.

**green** – The intensity of thegreen channel.

**blue** – The intensity of the blue channel.

**reset** – Resets all curves to default values.

 

> ℹ️ **Diagram and Gradient controls**
> ℹ️ 
> ℹ️ The following controls can be used in the color gradients and diagrams:
> ℹ️ 
> ℹ️ **Double click** – Creates a new point or changes an existing one.  
> ℹ️  **Left button drag** – Moves the selected point(s).  
> ℹ️  **Left button drag over the left or bottom rulers (diagrams only)** – Scale the diagram in the corresponding direction.  
> ℹ️  **Middle button drag over the background** – Drags the visible area. If the Ctrl key is pressed, the background can be dragged instead, thus transforming the diagram.  
> ℹ️  **Mouse wheel** – Zoom in/out. If the Ctrl key is pressed, the zoom will occur on the background instead, thus transform the diagram.  
> ℹ️  **Right click** – Brings out a drop-down menu where points can be added, edited, or deleted, fit the entire diagram or gradient into the view, clear the diagram, and load and save the diagram it to a file.

### **Output Parameters**

---

These parameters can adjust the transition between **Front Color** and **Side Color** over the Falloff Map's gradient.

**Invert** – Inverts the color values.

**Clamp** – Clamps the color values.

**Alpha from RGB intensity** – Takes the alpha information from the intensity of the RGB.

**Output amount** – Determines the alpha multiplier.

**RGB offset** – Allows a color offset to the produced RGB values.

**RGB level** – Determines the intensity of the falloff effect.

**Bump amount** – Defines how much bump is produced.

### **Example: Distance Falloff Type**

 

In the example below, the **Falloff type** has been set to **Distance** blend and mapped to the diffuse color of the V-Ray Material on the humbucker pickups on the guitar.
