Update:
Now working with streams (mp3/ogg) with peak and RMS levels (this demo is using an OGG stream) Looking into FFT for more details in future versions.
I've improved the overall lighting setup and added a nice synced floor.
Another thing is that I added VR support and it looks amazing in VR... could be something here
All the flare sprites have been converted to vectored planes for VR as well.
A lot of other little improvements - added occlusion masks to animated objects, as you can't raytrace through anims still
Started refactoring code to allow for a scene editor.
