Hi Alex, The RayTracedTechnique doesn't included checks against gl_ClipPane so doesn't support standard OpenGL clip plans as is. You could provide your own shader to do this,
The MultiPassTechnique is a lot more sophisticated and allows you to constrain the rendering volume to a convex hull geometry, it doesn't have support for gl_CliPlane though - again this could be added by custom shaders.
