Hi there! Is there any document or tutorial about Rendering on Another PC or Rendering on Network? Do we have to buy an extra render node? Thanks

Hello, Cityscape Pro comes with two types of licenses, a Workstation License, that has a User Interface, and a Render Node license that is used only for rendering. 

The license type can be selected during the installation. Render node licenses are unlimited and free, so you won't have to purchase additional licenses for your render farm.
