This page provides information on the VRayClipper node.

 

## **Overview**

---

VRayClipper is a geometric primitive that can be used to clip away parts of the scene with a simple plane or defined mesh object. It is a render-time effect and does not modify the actual scene geometry in any way.

## **Inputs**

---

**mesh** – An optional input that specifies a mesh object to clip against instead of the default plane.

**mtl** – An optional input that specifies a material for filling in resulting holes.

**excl**/**incl** – An optional input that specifies a set of objects to exclude or include from the clipper effect. The set type is controlled by the **Use exclusive set** parameter.

**Affect lights** – When enabled, the clipper will affect area light sources as well.

**Camera Rays only** – The clipper will affect objects as they are directly seen by the camera, but they will appear unchanged to reflection/refraction/GI rays.

**Clip lights geometry** – Enables or disables the clipping of lights' geometry (for example a mesh light).

**Use object material** – When enabled, the clipper will use the material of each clipped object to fill in the resulting holes. When this is disabled, the material connected to the **mtl** input will be used.

**Mesh mode** – Enables the clipper to clip with a mesh object rather than a plane. A mesh must be connected to the **mesh** input to enable this option.

**Mesh operation** – Determines how to use the mesh when **Mesh mode** is enabled:

**Intersection** – Clips away anything that is outside the specified mesh; only render objects and parts of objects inside the specified mesh are retained.  
 <span style="color: #000000">**Subtraction**</span> – Clips away anything inside the specified mesh; only render objects and parts of objects outside of the specified mesh are retained.

**Use exclusive set** – Toggles the exclusive/inclusive input set. When enabled, the set of objects connected to the **excl** input will not be clipped. When disabled, the **excl** input will switch to an **incl** input, and the clipper will only affect the connected set of objects.

 

## **Notes**

---

- VRayClipper works best with "closed" objects that have a corresponding back face. The results on open objects (without a corresponding back face) are not well defined.
- VRayClipper might produce artifacts if there are overlapping triangles in the scene, regardless of whether they are part of the same object or not.
