This page provides information on how to launch Chaos Arena. Loading Start the  Spawners   on all machines ( Render  and  Operator ) with the correct IDs, IP addresses, and paths to the renderer installations. Start the  Server   application. Load a  Configuration file  in the server using the  Open Configuration…  button. Press the  Start  button to allow the spawners to connect. Wait for all spawners to  connect  to the server.  When all spawners are connected and ready, a message is shown in the log,  then the  Open Scene…  button will become active. Load a  .vrscene file  from the  Open Scene…  button. The renderer should then start on the render and operator machines. Wait for the scene to load, first in the server and then in the render instances. When ready, the camera tracking should start working, and the statistics in the server should start updating. Control   the scene and the animation playback from the  Operator  instances if needed. Use the  DLSS mode  as the main control of the quality and performance. Adjust the  render   resolution multiplier in the  Arena Server  in addition to the  DLSS mode   for more control over the quality and performance. Import   another . vrscene  into the currently loaded scene using the  Append Scene…  button in the server if needed. Update  the configuration from the UI options and press the  Apply Configuration  button. The camera tracking options are applied immediately after pressing  Apply Configuration.  Most of the other options restart the rendering. Reposition  the stage geometry using the  Stage Position Node   option and the position offsets, or from an operator instance, by moving the stage geometry. Record  the camera tracking data to an Alembic file using the  Record Tracking  button. Use the  Stop Rendering  button to stop the rendering and close the scene and the render instances . Another scene can be loaded after that using the  Open Scene…  button. To  change the configuration , press the  Stop  button and then start the process again from step 3, or directly edit the configuration in the UI. A clean configuration can be started using the  Clear Configuration  button. Save  any changes to the configuration to a file at any time. To stop the server application, just close it at any time.
