RTTLayout2

RTTLayout2 is an editor for Falcon BMS 3dCkpit.dat RTT texture coordinate blocks.

What it does

• Opens a 3dCkpit.dat and display/edit RTT (Real-Time Texture) layout.
• For any RTT surface: select, drag, resize from corner handles, snap to the canvas edge, or manually edit dimensions.
• Detect and display collisions or out-of-bounds surfaces.
• Pan and zoom the canvas with middle mouse.
• Changes the rttTarget texture resolution and proportionally scales all RTT surface rectangles.
• Draws precise 1px inclusive borders so the preview matches the declared pixel extent.
• Can draw internal grids inside each surface to guide modelers/coders in accurate symbology placement.
• Allows surfaces to be moved outside the RTT target while editing, but blocks export until they are brought back inside.
• Can prevent overlap while editing when Allow Overlap is unchecked.
• Saves a clean, aligned RTT block back to 3dCkpit.dat if desired
• Exports the layout as PNG at native, 1k, 2k, 4k, 8k, or custom resolution for accurate UV map application.
• View HUD projection metrics and adjust multiple parameters to achieve accurate HUD field of view

Run

python RTTLayout2.py
python RTTLayout2.py "C:\Falcon BMS 4.38 (Internal)\Data\Art\CkptArt\F-15C\3dCkpit.dat"

The app only needs Python with Tkinter and Pillow.

Package As A Windows EXE

python -m pip install pyinstaller -r requirements.txt
python -m PyInstaller --noconsole --onefile --name RTTLayout2 RTTLayout2.py

Next Extension Points

• A future 3dButtons.dat editor should get its own parser/model module and a new UI tab, reusing the same validation and export patterns.
• Sound table support should be implemented as a separate resolver service so button editing can remain independent of audio playback.
