This page provides information about the Displacement in V-Ray for Rhino.


## **Overview**

---

Displacement mapping is a technique for adding detail to your scene geometry without having to model it first. The concept is very similar to [bump mapping](https://docs-chaos.atlassian.net/wiki/spaces/VRHINO/pages/116129969). However, bump mapping is a shading effect that only changes the appearance of a surface, while displacement mapping actually modifies the surface.

### **Example: Shift**

Note that the **Shift **parameter is an absolute value in world units. If you change the **Amount**, you will probably need to adjust the **Shift **too.

### **Example: Keep Continuity**

** **The **Keep Continuity** option is useful for objects with disjoint normals on neighboring triangles, usually because of different smoothing groups. In the middle image below you can see the edge splits produced by disjoint normals. Using the **Keep Continuity **option avoids this problem. This option also helps to produce a smoother result across material ID boundaries for objects that have been assigned MultiSubObject materials.

### **Example: Edge Length**

** **This example shows the effects of increasing the **Edge Length** parameter. In this example **View Dependent** is enabled, so **Edge Length** is expressed in pixels. In the examples, the closeup view is a blow-up rather than a zoomed view. This means that **Edge Length** in the closeup view refers to pixels in the original image, not the blow-up rendering. Click the images for a larger view.

The image below was rendered with a V-Ray Edges map in the Diffuse slot of the material to show the original triangles of the mesh.

### **Example: Level Height**

** **The **Level Height **parameter is absolute in world units. For this example, **Amount** is set to 5.0 and **Shift **is set to 0.0. Note that when **Level Height **reaches **Amount** + **Shift**, all geometry is clipped.

## **Notes**

---

- The **2D mapping (landscape)**  method only supports one UV mapping channel.
- Starting with V-Ray 5.20.01, V-Ray special objects (Fur/Clipper/Displacement/Mesh Light/Scatter) are not deleted from the Asset Editor, when the last item with the corresponding special object assigned to it, is deleted from the viewport.
