Corona Renderer Helpdesk for 3ds Max plugin

Does Corona support network rendering?

Yes it does. You can network-render using Autodesk Backburner and Thinkbox Deadline, or use Corona's integrated DR solution.

See: How to use Distributed Rendering?

Generally, Autodesk Backburner should be used in "each PC is rendering a single frame" scenarios, while Corona's DR works by rendering a single frame across all PCs in the network simultaneously.
