   Bump on this.
   This could be established by giving the user the option to show it in an actual window rather than as an overlay.
   This way OBS could recognize it as a window and allow the user to add it as a source.

   Hi there! 👋

   I (@doggy8088 / Will Huang) have stepped in to take over active maintenance of Carnac at doggy8088/carnac (project website: https://carnac.gh.miniasp.com/).

   This issue regarding capturing Carnac in OBS Studio, XSplit, and Windows Game Bar (and keeping the overlay topmost) has been resolved in my fork!

   Context & What Changed

   • Root Cause: KeyShowView previously unconditionally set the Win32 WS_EX_TOOLWINDOW extended window style (to hide the overlay from Alt+Tab). Because OBS Studio, XSplit, and Windows Game Bar skip tool windows when enumerating capturable windows, Carnac did not appear in Window Capture source lists, and layered transparent windows without an optional solid chroma-key background were difficult to composite over arbitrary regions.
   • The Fix (Add a capture-friendly window setting for OBS and XSplit doggy8088/carnac#41):
     1. "Show Overlay in Window Capture (OBS / XSplit)" Toggle: Added ShowInWindowCapture in Preferences -> General. When enabled, Carnac removes the WS_EX_TOOLWINDOW flag and registers a titled window (Carnac Overlay) that OBS Studio, XSplit, and capture tools can pick up directly as a Window Capture source and reposition anywhere on your stream canvas.
     2. Chroma-Key / Capture Background Color: Added an optional Overlay Capture Background setting so streamers using Window Capture can apply a clean chroma key or solid background if needed, while keeping the overlay topmost (Topmost = true).

   Availability

   • Source Code: Available now on the dev branch of doggy8088/carnac.
   • Upcoming Release: This will be included in the next official release, which will be published to GitHub Releases (both installer and portable .zip), WinGet (winget install doggy8088.Carnac), and Chocolatey.
