I am participating now in such project - 3D CAD alike application: it renders 3D scene in Vulkan with Sciter rendering auxiliary UI on the same Vulkan surface. Sciter manages dockable widgets, property editors, scene tree logical representation, menus, etc. on top of 3D scene. Approach is explained here: https://sciter.com/sciter-and-directx/ https://sciter.com/sciter-and-directx/ You see there exactly 3D, video and GUI around.
