Know that the project is not abandoned at all, here you can see the state:
I have not uploaded any more updates because I have removed almost all the objects and buildings that will be replaced by the final realistic version in 3D once recreated. Uploading the current version without buildings seems illogical to me and therefore I am waiting to finish at least the buildings and main objects to provide a minimum immersion. Understand also that I have had to learn to use Blender from scratch and the SDK is giving me many problems running at 5 FPS so it is a very complicated and slow task to continue with it. I think it’s a problem when taking the menus out of the SDK to other PC screens.
