VRC Quick Launcher
VRC Quick Launcher (VRCQL) is a utility tool designed to enhance the user experience for VRChat developers and power users by providing an advanced method for launching multiple VRChat instances and managing various settings through a graphical user interface. This is part of VRChat Creator Companion.
you can specify the file location of VRChat, this allows you to have multiple builds of VRChat. VRCQL will remember the last 10 builds used, this means you can easily access and use VRChat & VRChat Open beta for example.
Launch options
VRC Quick Launcher has several Launch options, these work similar to launch options on steam.
| Option | description |
|---|---|
| Debug GUI | When enabled you will be able to use the Debug Menus. |
| SDK log | Enables a large amount of additional logging. This can cause your log file to get very large. |
| UDON log | Logs udon events to the log file, this will also show extra information in world debug menu 3. |
| Watch worlds | Watches the location where the VRChat SDK builds worlds, and automatically joins any new local world created. |
| Custom parameters | |
| MIDI | Forces the MIDI drive to search for a connected MIDI device which contains the deviceName specified, including partial matches, case-insensitive.
|
| OSC | Modifies the port or IP address VRChat uses for OSC using the format 'inPort:senderIP'. |
| Max FPS | Allows you to set the max fps any instance of VRChat can run at. |
| Watch Avatars | Watches the location where the VRChat SDK builds test avatars, and if wearing a test avatar that's been updated automatically switches to the newer version. |
| Legacy FBT caliibration | Enables using the old locked avatar position style of FBT calibration instead of the current IK2.0 calibration. |
| Disable shoulder tracking | Prevents arm trackers from affecting shoulders. Use this to avoid issues with some types of IMU-only based arm trackers. |
| Enable IK debug logging | Adds additional output to the log regarding IK. Use this when reporting bugs or issues with IK. |
| Freeze tracking on disconect | Cause trackers to freeze in place relative to the user when they are disconnected. |
| Custom arm ratio | Adjusts the ratio used to scale the avatar when using measure-by-arms mode. |
| Calibration range | Determines the distance from predicted supported binding points that the calibration will search (in meters). The default value defines a 0.6 meter (60 cm) sphere. This applies to feet, thighs, hip, upper arms, and chest trackers. |
Instance info
With VRC Quick Launcher you can choose what instance type you wish to launch the game into.
| Option | description |
|---|---|
| Create | This allows you to create an instance with options to set the instance type, specify a world ID (leave empty for default home), specify an instance ID, set a user ID for the instance owner, and specify a region. |
| Join | This allows you to join a specific instance using an instance link. |
| Local | This creates an instance of a local world in offline testing mode. This version of the game does not start with Easy Anti-Cheat and cannot visit non-local worlds. |
| None | This will open to your home world. |
Profiles
Profiles allow you to launch multiple instances of VRChat simultaneously. You can specify which profiles to launch and whether they are in VR mode or not. Two or more instances of the same user can exist in a local offline world but cannot join the same online instance. It is possible to setup an infinite number of profiles, you can launch them individually in a group or all at once.
Enabling "Auto-layout" arranges all windows on the main monitor so you can see all instances of VRChat at the same time.
How to set up multiple installations
Here are the steps to set up multiple profiles to work with VRC Quick Launcher VRCQL:
- Create a folder to hold the version of vrchat you are going to use.
- Go to "C:\Program Files (x86)\Steam\steamapps\common" in your file browser.
- Copy the folder named "VRChat" into the folder you created earlier, this will create a copy of your currently installed version of VRChat. that VRCQL can open.
- open VRC Quick Launcher VRCQL
- Click "Browse" at the top right
- select VRChat.exe from the new folder
This installation of VRChat will now appear in the drop-down menu. When this installation of VRChat is selected, it will launch the copied version of VRChat. This means if you were on the Open Beta on Steam, you can revert to the Release version and still launch the Open Beta from VRC Quick Launcher VRCQL. However, the copied version of VRChat will not update automatically.
