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

Creating Mesh Clipper

The Mesh Clipper can only be applied to group or component objects in SketchUp (sometimes referred to as closed geometry). After creating a Mesh Clipper object, a bounding box with a Mesh Clipper icon will appear in the viewport around the selected group or component. The bounding box and icon represent the newly applied Clipper object properties.

The Clipper object can be copied between groups or components by placing them inside a new group or component. The object will then receive all associated object properties.

By applying a material to the group or component, the Clipper object will absorb the applied material and use that applied material and UV Mapping for the clipped faces.






Enabled – Turns the clipper effect on and off.

Mode – Enables the clipper to clip against an arbitrary group or component rather than an infinite plane in one of two ways. 

          Subtract  Clips away anything inside the specified group/component; only renders objects and parts of objects outside of the specified group/component.
– Clips away anything that is outside the specified group/component; only renders objects and parts of objects inside the specified group/component. 

Use object material – When enabled, the clipper will use the material of each clipped object to fill in the resulting holes. When disabled, the material applied to the clipper object itself will be used.

Material – Specifies the material used by the clipper.  This option is not accessible unless the "Use object material" setting is disabled.

The input slot () of the Material has a context menu available when you right-click on it. You can also drag-and-drop materials into the slot. 



You can CopyCutClear the selected material or Paste as Instance another material into the slot.  

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

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

Clip Light Geometry– When enabled, the clipper will clip light geometry (for example a mesh light).




  • VRayClipper works best with "closed" objects. The results on open objects (without a corresponding back face) are not well defined.
  • Currently the VRayClipper may produce artifacts if there are overlapping triangles in the scene, regardless of whether they are part of the same object or not.
  • V-Ray matches a Section Plane's name only upon its creation.
