## Shader changes
Mapbase uses shader code from the aforementioned projects, including Alien Swarm, G-String, City 17: Episode One, etc. The shader changes alone fix most of the bugs the VDC fixes couldn't fix, including the "reverse projection" bug and the bug with decals not receiving casted shadows.
