Affect Light – Enables the clipper to also affect area light sources.
Clip Lights Geometry – Enables the clipping of lights geometry (for example a mesh light).
Only Camera Rays – The clipper affects objects as they are directly seen by the camera, but they appear unchanged to reflection/refraction/GI rays.
Fill Inner Cavities – When enabled, shades the clipped part of the object with the clipper object's shader.
Use Object Material – When enabled, the clipper uses the material of each clipped object to fill in the resulting holes. When disabled, the material applied to the clipper object itself is used.
Mode – Specifies how Objects list items are clipped. You can include or exclude an object(s) from the clipper effect.
Objects – Specifies a list of objects that are affected by the clipper.
Mesh Operation – Determines how to use the mesh when a geometry is selected as a clipper:
Intersection – Clips away anything that is outside the specified mesh; only renders objects and parts of objects inside the specified mesh; Subtraction (scene-mesh) – Clips away anything inside the specified mesh; only renders objects and parts of objects outside of the specified mesh.
