Vray spawner

[komyali]

When you use vray spawner for distributed rendering on multiple machines, light cache is calculated only on local machine, while irradiance map have only one pass but buckets are from all network machines, and irradiance buckets look different from different machines. I done couple tests and didnt find any difference from distributed rendering and regular rendering, although long time ago somebody told me on forum that best option is to render prepasses on local and then use them on distributed renderin. My question is: Is there a difference with irradiance map rendered on distributed or local ? And does it impact quality of final rendering?
