EDMC Modern Overlay (packaged as EDMCModernOverlay) replaces EDMCOverlay and edmcoverlay2. It is a cross-platform (Windows and Linux) plugin for Elite Dangerous Market Connector (EDMC). It streams data from other EDMC plugins to be displayed in your game window. EDMCModernOverlay supports fullscreen, borderless, and windowed mode on any display size. It also now has a standalone mode as an experimental feature in 0.7.7 for use in SteamVR. The plugin releases include Windows (powershell and .exe) and Linux installers.
CMDRs can customize the placement of plugin payloads on their game window using the Overlay Controller. You can change X/Y placement, anchor point, text justification, and add/change background colors for each plugin display.
Plugin authors can leverage EDMC-ModernOverlay's flexible payload system to precisely control where their overlays appear. By specifying properties like anchor, justify, explicit X/Y coordinates, and backgrounds 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.
