ITC v4.7.6 is now available. The legacy FWL 3.2 version has been discontinued. Feel free to message me directly if you need the FWL 3.2 version.
NOTE: Due to the ongoing updates to xplane.to, I'm unable to respond to comments as there is no option to do so that I've found. I will respond in the future whenever the feature is restored. I appreciate all feedback, questions, and feature requests, and look forward to having the chance to respond.
ITC v4.7.6 has been released. A host of development changes to make ITC more self-sufficient and to reduce cycles between updates.
Due to the very involved back end development process for this update, there may be bugs. Please report bugs to me directly on xplane.to or on the ITC Discord channel.
You can use the "Install Update" option to save your presets/settings files, or simply copy itc.xpl from the download folder to resources/Plugins/ITC and replace the file.
Bug fix updates and X Plane compatibility patches for ITC will continue for the foreseeable future.

ITC Light Mod with ITC night lighting.
---------------------------------
ITC has been completely rewritten, and is now a standalone plugin. It does not require FlyWithLua, Reshade, Nvidia filters, or any other library to work. Simple drag and drop installation, or use the included installer.
ITC allows you to customize X Plane 12's lighting and atmosphere. It also includes night lighting enhancements for a more realistic look.
Key features:
Adjust intensity of night lighting to suit your preference.
Adjust daytime lighting and atmosphere.
Adjust intensity of night sky.
Save and load up to three presets, with keybind support (search ITC in keybind menu).
Set a default preset to load when X Plane starts up.
Adjust cloud size, scale, and shape.
Change color of far night lighting in real time.
The plugin is fully compatible with other lights.txt mods and default lighting and has an Advanced Settings option to disable specific dataref controls, allowing experienced users to create compatibility profiles with other mods/scripts.

Note screenshots represent custom values, they're used to give an idea of what types of changes can be achieved. Find your own preset and use that!
The mod is versatile. You can use just the lights, just the plugin, your own lights, other light mods, or any combination. It's up to you.
To Update ITC:
Use the new "Install Update" feature in the ITC Installer, or manually copy itc.xpl from your downloaded folder to the Resources\plugins\ITC\win_x64\ folder. Replace the file when prompted.
Automatic Installation:
Open the ITC Installer.exe. Select components to install, and click the Install button. Navigate to your X Plane 12 root folder (the folder containing X-Plane 12.exe, if the installer doesn't find it automatically), this folder is usually:
C:\X-Plane 12 for standalone, or
C:\Program Files(x86)\Steam\steamapps\common\X-Plane 12 for Steam users.
NOTE: Your X Plane 12 installation folder may vary. The installer will prompt you if it doesn't find the correct files.
Hit OK and let the installer copy files and you're done.
Manual Installation:
Unzip the zip file and copy the entire "ITC" folder to your Resources\plugins folder for X Plane 12. NOTE: Check for a sub folder after unzipping. The folder structure should be ITC\win_x64\, not ITC v4.5\ITC\win_x64.
For the optional light changes:
Go to C:\X-Plane 12\Resources\bitmaps\world\lites and make a backup copy of lights.txt and 1000_lights_close.png, then copy the files from the Optional Lights folder and paste them into the C:\X-Plane 12\Resources\bitmaps\world\lites folder.
--
Make a copy of default files prior to installing. If you have issues with the mod, you can restore default files:
On Steam, go to your Library, right click X Plane 12, select Properties>Local Files, and click Verify Integrity of game files.
On Standalone, go to your X Plane 12 folder and run the X Plane 12 Installer, click to Update, allow it to scan files, and when prompted, allow it to replace old files.
--
Launch X Plane and find it under Plugins>ITC Light Mod>Main Window.
To use preset keybinds:
Go to your keybind menu and search for "ITC." They may be at the bottom of the list. You can load presets without opening the ITC window.
To use the jetway sounds:
Search your keybinds for "ITC Jetway" and bind a key/key combo to that. Jetways will activate and play relevant sound files. Some aircraft have jetway sounds built in. In that case you can use the default keybind, "Service the airplane with Jetways." Choose your own keybind or use both, it's up to you.
To modify jetway volume, go to the Extra Options menu and set your desired volume level. Jetway volume is saved to your presets.
Note: Jetway sounds are compatible with default airport jetways. SAM and Autogate jetways play their own sounds and will not activate with the ITC Jetway keybind or the default keybind.

FAQ:
Q: My screen is flickering after installing ITC. What's going on?
A: It's most likely a lua script conflict. Many visual enhancing lua scripts operate every frame, and that causes the screen flickering. Disabling cloud controls may resolve the issue, otherwise removing the Lua script, or ITC will fix the problem.
Q: Is ITC Light Mod compatible with VR?
A: Partially. The changes made with the mod are fully VR compatible, however some headsets may not display the floating ITC window. It's recommended you make changes outside of VR, save a preset, then load it when you're in VR with a keybind. Hopefully full VR support will be in a future version.
Q: Is ITC compatible with 4k?
A: Yes, partially. However, if you're using a UI scale of 150%, you will not be able to interact with the ITC window. It's recommended you lower the scale temporarily to 100%, make changes in ITC, and save your presets. There may also be some UI issues. Full 4k support will hopefully be included in a future version.
Q: I have a "notice" message in ITC and I can't make any changes. What's going on?
A: Reducing your UI scale to 100% in X Plane settings will resolve the issue. Currently, ITC does not support 150% UI scaling. The notice is there to let you know of the issue and how to correct it.
Q: Is the ITC Installer a virus/malware? Windows Defender is warning me about it.
A: No, it's not malware. xplane.to scans every file for viruses. The installer copies files to and from folders, which triggers Windows Defender's threat protection. You can click "Run Anyway" to bypass this. If you're not comfortable running it, manual installation is a simple drag and drop process.
Q: Are there plans for a Linux or Mac version?
A: Currently there are no plans to port ITC to Linux or Mac. As much as I would like to do that, I unfortunately don't have time to set up a Linux dev envirornment, and I do not own a Mac, which makes Mac development impossible.
Q: How can I get help with the ITC Light Mod?
A: Join the Discord: ITC Discord
