LMU uses "Plugins" to extend it's features and to collect telemetry, we'll need you to install one.
The "Install LMU Plugin Automatically" button on the Desktop App will add the require telemetry DLL to your game so that the telemetry data can be read by Track Titan.
If you'd prefer to install the plugin yourself please follow the instructions below. It will require you to do a bit of JSON file editing and you should be capable of finding the folders for your steam apps.
How to Manually Install the LMU Track Titan plugin.
First, download the DLL
Track Titan LMU Telemetry Plugin
This is message will probably be displayed as the file is a .dll - 'Download unverified file'
Save this in the LMU Plugins folder :
This is : {STEAM ROOT}\steamapps\common\Le Mans Ultimate\Plugins
Update the Plugin configuration file :
This is : {STEAM ROOT}\steamapps\common\Le Mans Ultimate\UserData\player\CustomPluginVariables.json
Add an entry for the the Track Titan plugin:
"TrackTitanRf2Plugin.dll":{"Enabled":1} [CODE]
Your json file may look like :
{"TrackIR_LMU_Plugin.dll":{"Enabled":1},"TrackTitanRf2Plugin.dll":{"Enabled":1}} [CODE]
NOTE : {STEAM ROOT} is the Steam installation folder (commonly C:\Program Files (x86)\Steam)
