Sampling


Subdivs – this value controls the number of samples V-Ray takes to compute lighting. Lower values mean more noisy results, but will render faster. Higher values produce smoother results but take more time. Note that the actual number of samples also depends on the DMC Sampler settings.

 

Io fossi in te inizierei ad alzare i sampling che ti conviene andare sempre di multipli (8, 16, 32, 64....etc...), poi se vuoi proprio eliminare il noise devi agire sui parametri dell'Irradiance Maps con valori personalizzati....

è un po' vecchio ma questo tutorial/articolo aiuta molto
