Since the last update, some thing shave changed.
The main fix included is that the skybox from the mirrored cubes were causing issues on any scenario and terrain which used small grid pure. Unfortunately, there is little I can do to make the glass more see through so the glass has been left alone.
Also, regarding the V3 update: there likely will not be a V3 update as this mod is becoming really difficult for me to work with and I am really not enjoying updating it. That being said, I will (possibly) may update this mod in due course but at the moment I am not going to be doing anything with it in the near future.
