Are studio just upgraded to max 2015, forest 4.3.6, vray2 2015. Are workstations "WS" and rendered farm "RF" are from boxx. Forest works great on new scene at least for test but on a old scene its a different story. If I render the scene without forest WS are at 2min 20 sec and RF are at 1 min 50 sec. But once I turn forest on the WS are at 2 min 50 sec and the RF are at 14 min. I tried recreating the forest in the scene but same issue. Any help would be great.
