Template:StandaloneCommandLineArguments

You have two options:

Using the Neos Launcher

1. Find the Neos Launcher for the standalone. You can do this by double clicking on the NeosLauncher.exe in the NeosVR install folder
2. Check the "Use custom bootstrap class" option
3. Enter your command line arguments in the box below this checkbox.

Launch arguments entered this way will only take effect if the Neos Launcher is used to start Neos.

Use a shortcut

It is possible to use launch commands via a custom shortcut targeting the Neos.exe file.

To create a shortcut:

1. Find the Neos install folder and right-click on the Neos.exe.
2. In the context menu click 'Create Shortcut'
3. Move the 'Neos.exe - Shortcut' file to somewhere more convenient (such as the Desktop).
4. Right-click on the shortcut file and click 'Properties' in the context menu.
5. This opens a dialog window. Select the 'Shortcut' tab.
6. In the 'Target' text box add a space after the Neos.exe filepath and then add your command line arguments.
7. Click 'Apply' and 'OK'.

Now, if Neos is launched by double clicking on the shortcut it will launch using the custom options. These will not be applied if a different method is used to start Neos.
