User Presets

Profile Creation Steps:

  1. Modify or copy and create user preset(s) in default_config.json (or preferably in the Game.exe_config.json if one already exists) for the game you want to play
  2. If applicable, modify hmd_height, fov, pitch_enable, yaw_enable, pose_reset_key, ctrl_toggle_key, ctrl_toggle_type, pitch_radius, ctrl_deadzone, ctrl_sensitivity for the game profile
  3. If the game is already running, use Ctrl + Shift + F10 to reload the default_config.json (or Ctrl + F10 to reload the Game.exe_config.json) with your new settings and presets
  4. Adjust depth/separation (Ctrl + F3 and Ctrl + F4 with + shift if possible) & convergence (Ctrl + F5 and Ctrl + F6) for a preset
  5. Use the configured user_store_key to temporarily save the current depth/separation & convergence values to the preset
  6. Repeat 4 & 5 for each preset you need
  7. Adjust depth/separation & convergence back to what you want the default to be (if you have a default "switch" preset, you can use its configured user_load_key)
  8. If applicable, adjust the ctrl_sensitivity with Ctrl - and Ctrl + and the pitch_radius with Ctrl [ and Ctrl ]
  9. Save the profile with Ctrl + F7
  10. Open your new profile from Steam\config\vrto3d\ in a text editor and make final adjustments like: making all the convergence values match to avoid rendering or performance issues, changing virtual-key mappings, or tweaking other values/settings
  11. Close out of SteamVR and the game and restart the game. You should hear a loud beep to indicate the profile loaded. Test the profile and you can still make any adjustments per above instructions
  12. Share your Steam\config\vrto3d\Game.exe_config.json with others
