Any thoughts on adding VR support to this?
None at the moment no, it's very much more focused on being a 3D VN Creator/Player. You will be able to create dialogues, animations, etc. all inside the software and then share your scenario with only one small-sized file! It's less about physical interactivity than freedom and creativity!
I love VR but this is not the project for it! :D
Based on what i'm reading it seems like maybe the Scenario Player is a separate program and launcher? If so you could potentially make a forked version and design/ implement VR controls & UI for it.
I imagine that no matter what a VR UI for a scene editor/creator is gonna end up kinda clunky, so that could probably be skipped.
