While ideally this should be infinite, in practice a smaller number of bounces may be sufficient, or some light interactions may be intentionally left out for faster convergence. It also includes a very efficient caching mechanism. A value of 0 bounces results in direct lighting only. Glossy Maximum number of glossy bounces Light paths are terminated probabilistically when specifying a minimum number of light bounces lower than the maximum.
