This page provides information about the Clipper in V-Ray for Grasshopper.
Overview
The V-Ray Clipper is a special object that can be used to clip away parts of the scene with a simple plane or with a custom mesh shape. It is a render-time effect and does not modify the actual scene geometry in any way.
Use a standard Grasshopper plane object as an input to create a render-time section plane. Use any other closed mesh as an input to create a mesh clipper (boolean modifier).
Input Parameters
Clip Mode (Integer) – When set to Subtract (1), everything inside the specified mesh is clipped away (only for mesh clippers). When set to Intersect (0), everything outside the specified mesh is clipped away.
Geo (Generic Data) – Expects either a plane, a mesh, or any geometric object input (including V-Ray Geometry). A closed mesh should be used for best results. It is recommended to use native Grasshopper geometry.
Use Object Mtl. (Boolean) – When enabled, the clipper uses the material of each clipped object to fill the resulting cuts. When disabled, the material applied to the clipper object itself is used. If no material is specified in this state, the clipped gaps remain empty.
Mtl(Generic Data) – V-Ray Material input is expected in this slot.
Excl. Mode (Integer) – When set to Exclude (1), all scene objects are clipped except for those in the Exclusion List. When set to Include (0), only the listed objects are clipped.
Exclude (Generic Data) – List of V-Ray Geometry objects considered for exclusion or inclusion.
Affect Light (Boolean) – When enabled, light can pass through openings created by the clipper.
Cam. Rays Only (Boolean) – When enabled, clipped objects appear unaffected in reflections, refractions, and GI.
Output Parameters
V Geo (Generic Data) – A V-Ray Geometry output that can be connected to the V-Ray Render component.
