This page provides information on the V-Ray Clipper.

Page Contents


Overview


V-Ray Clipper 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.  

 


 

UI Path: || V-Ray Toolbar || > Add Clipper plane button

 

Left-click to add Clipper plane.

Right-click to link Mesh to Clipper. 

Parameters


 

 

 

Main

 

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.
          Intersect 
– 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.

 

Options

 

Affect Light – When enabled, the clipper affects light sources. 

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

Clip Light Geometry – When enabled, the clipper affects light geometry (like mesh lights). 

 

Exclude/Include Named Objects


Specifies a list of objects that can be included to or excluded from the V-Ray Clipper's effect. Only V-Ray geometry and named objects are listed.

 

Notes


  • V-Ray Clipper works best with "closed" objects. The results on open objects (without a corresponding back face) are not well defined.
  • Currently, the V-Ray Clipper may produce artifacts if there are overlapping triangles in the scene, regardless of whether they are part of the same object or not.
  • The Exclude/Include option will only work with named geometry. The user will have to manually assign a name of the object they want to appear in the exclude/include windows.
  • Clipper objects can be copied either using the Copy tool or by using the Gumball selector and holding Alt + Left click to drag the Fur Object.
  • Clipper objects can be Linked or Unlinked from one or more objects in the V-Ray tab in the Rhino Properties Panel.
