EDMCModernOverlay is a drop-in replacement for EDMCOverlay and edmcoverlay2. It is a cross-platform (Windows and Linux), two-part implementation (plugin and overlay-client) for Elite Dangerous Market Connector (EDMC). It streams data from EDMC plugins over a lightweight TCP socket and displays a transparent, click-through PyQt6 heads-up display on the Elite Dangrous game. It runs in both fullscreen borderless and windowed mode on any dispaly size. The plugin releases ship with both Windows and Linux installers.
EDMCModernOverlay also allows CMDRs to define custom placement of plugin HUD elements it recognizes with an easy to use interface. You can manipulate anchor point, X/Y coordinates, and text justification (left, center, right). Type !ovr in the in-game comms panel to launch the controller.
Plugin authors can leverage EDMC-ModernOverlay's flexible payload system to precisely control where their overlays appear. By specifying properties like anchor, justify, and explicit X/Y coordinates in their group definitions, authors can define the placement, alignment, and justification of HUD elements relative to any corner, side, or the center of the screen. The overlay interprets these fields to allow left, right, and center justification, vertical/horizontal anchoring, as well as pixel or percentage-based coordinates for fine-grained positioning—enabling complex, fully-customized HUD layouts for different use cases.
