I have 12 machines but don't have the grid yet. I'm wondering if it is worth it? I think that two changes would make network rendering better. One, the source computer should go back and try to render any tile that the network has sent to finish. If a slow machine get a tile to render that is very complex, like dynamic hair, then it's almost faster to let the fastest computer to render everything. Two, have two frames rendering at once. The other nodes can move on to the next frame instead of waiting for the last few tiles to finish. Dale
