Render Settings

The rendering tab displays information for the engine settings, clay render mode, network rendering, devices and more.


The engine settings panel adapts to the selected engine. You may find detailed information for the Thea Render Presto and Nitro engines.


The devices rollout displays the supported devices that have been detected on the system. Including any processors and graphics cards. Devices can be enabled or disabled and have their priority changed.

  • Priority: This value should be left at its default value (Low) since this will allow the operating system to allocate resources when needed and avoid any lagging.
  • Split frame workload evenly: This option should only be used when the system is equipped with multiple identical graphics cards. When enabled, Thea for SketchUp will split the rendered image to the total number of enabled graphic cards making interactive rendering more fluid.

Performance tip: If the machine you are working on has multiple graphics cards, it is best if you disable the GPU used by the operating system.



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, clipping and transparency can still be seen in the final render.

  • Reflectance: Increases - decreases the diffuse material reflectance (from black to white)


Clay render


Network rendering is only available in production rendering. To render a scene with the help of the nodes of 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 enough; 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.
  • Animation cooperation:
    • On same frame: Cooperating on the same frame. All machines contribute to the current frame
    • On individual frames: Cooperating on different frames. Each machine processes fully a frame that is part of an animation sequence


For more information on network rendering, go to the network rendering page.


  • 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
