ImGUI Basics

To show ImGUI in Skia or Stride we need to install the dependencies VL.IMGUI.Stride/Skia.

You then put all the UI elements in an IMGUI Region. The Region has a render output at the bottom which we then need to connect to RenderEntity in Stride. To show the UI over the Stride content we need to set at the RenderEntity Renderstage to After Scene.

Inside the Region we then place our ImGUI Widgets like Slider or Button. They need to be chained into each other.

We can also visually group our UI widgets in the Window node.
