network rendering with vray

To do network rendering with vray do you have to have a copy of Vray on all machines. Or just the machine that has controll of the rendering? Is vray multi treaded when caculating the photons or IR Map or just the rendering its self.

from what i see its fully multithreaded. to the point of having 4 cubes working on irradiance maps when using dual HT chips
and yes you need vray on all computers

Thanks Da_elf. But what is HT chips. I have a dual 2.6ghz machine are they ht?

is it a dual intel xeon?

HT means HyperThread if you are running a Dual Xeon 2.6 you should in theroy have HT Processors. Open the task manager and click on the Performance tab and see if you are showing 2 or 4 processors. Also you have to be running Windows XP Pro or the newer Windows Servers to fully benefit from the HT Technology. If you are running Win2000 then it will only see 2 Processors as it doesn’t take advantage of HT.

Hope that helps a little.
