Hi,
i just tried it for 4.19. But somehow the plugin is downloaded for 4.18 (https://bitbucket.org//vrexpansionplugin/downloads/). And when i open my 4.19 project, the plugin shows 4.18 indeed. And i am not able to get the whole map in the project. It just opends as a blank project. I can remember that the first time i did , that your whole example project opened. Do i make a mistake?
