The default options usually work for different scenes, but if access to more advanced options is needed, the right-hand side panel of the Asset Editor provides those. V-Ray Settings are organized in two panels - the main one exposes the default options for a scene setup. They can be accessed from the Asset Editor in the Settings tab. V-Ray Settings provide control over the parameters that adjust the rendering process.
This page introduces the render settings in V-Ray for Rhino.
