It is difficult to say if 16GB will be enough for rendering heavy scenes since people have different opinions for “heavy scenes”, for some people 16GB might mean medium scene for others it might be a heavy scene. > [@On another topic](https://forums.chaos.com/t/47519/7): > > how many nodes can be used to render a scene? > (theoretically) I don’t think that there is a limitation for the number of the machines participating in DR but from practical stand point using too many machines is not very efficient since sometimes the first machines that receive the dr-job completes the entire image while the other ones still receiving the data. > [@On another topic](https://forums.chaos.com/t/47519/7): > > Sometimes, and especially with heavy scenes, after the step of calculation of GI (IR + LC)… I have the problem of the black squares in the final process of rendering.

The above is valid for V-Ray 2.x - with the release of version 3.x the License policy has changed. --- _[View the full topic](https://forums.chaos.com/t/distributed-rendering-computer-advice/53932)._
