The Ca3D-Engine is a modern game engine and game development kit with 3D real-time graphics and multiplayer network support for Windows and Linux.
The new version introduces a new GUI Editor, a convenient graphical editor for editing GUIs for use in Ca3DE. The resulting GUIs can be used both in 2D (e.g. for the console, player HUD or the main menu) as well as directly in the 3D worlds as game elements.
