The Rendering Tab displays the selected engine parameters along with every other common render setting like the Devices List, Network Rendering, etc.
In this section, only the selected engine's settings will be displayed. You can find detailed information about each engine in Render Engines.
Provides a list with all devices that have been detected on your system. That includes the CPU and any NVIDIA/AMD graphics card. It is possible to enable/disable devices individually and set the priority of each. It is best to disable the GPU that is being used by Windows for machines with more than one GPU.
By enabling this option, all materials in the scene will be rendered as diffuse gray, giving the final image a clay effect. Material properties like bump and clipping can still be seen in the final render.
Reflectance: Increases/Decreases the diffuse material reflectance (from black to white).
Network rendering is only available when in Production Mode. To start using machines on the local network, enable Network Rendering by clicking on the checkbox.
Server Mode: There are two options to choose from. "Render and Manage" makes the server machine render along with the rest of the nodes. "Manage Nodes Only" should be used when the server is not powerful; this way, the server doesn't execute the rendering itself but just exchanges data with nodes.
Server Port: The default value is 7200 and is used for communication between the SketchUp (server) and nodes.
For more information on Network Rendering can be found in Network Tab.
Threads: Refers to the worker threads used during rendering. While the default value is set to Max, you can use the drop-down to select the preferred amount of threads.
Priority: This parameter corresponds to the priority assigned to render threads by the operating system. Select 'Normal' to make rendering faster; however, 'Normal' is not recommended when you use the machine in parallel or run other demanding processes.
