Here’s an update on a city builder app that I’m currently making with Litho. This app includes a menu structure and object spawner. You can multiply buildings and roads to build a complete city. Up next will be driving cars and possibly planes with an airport.
This is definitely in our pipeline, unfortunately, Litho City was developed at the same time as the SDK and is not quite compatible with our current SDK. Therefore it will be problematic to integrate into your scene.
I’m glad you like the menu structure, it was definably created with various spatial applications in mind. I’m happy to answer any of your questions on how to make a similar UI framework.
