env_global_light is an orthographic projected texture, like an env_projectedtexture that only casts shadows in one direction. This is another thing Insolence ported that ended up being gleaned into Mapbase. I have taken a few liberties with it, like setting the offset cvars to 0 and turning them into keyvalues instead.

This is another thing Insolence ported that ended up being gleaned into Mapbase. I have taken a few liberties with it, like setting the offset cvars to 0 and turning them into keyvalues so amppers can control it, but I don't really expect it to be used very much.
Again, you can thank Insolence for this, not me.
### Dynamic RTT shadow angles

Mapbase uses Saul Rennison's dynamic RTT shadow angles from the VDC, implemented from Insolence commits. Dynamic RTT shadows angles are off by default and must be enabled through an input/keyvalue in shadow_control, an option which Insolence seems to have added themselves.
(Dynamic shadow angles discussion, thank Saul Rennison and Insolence)
There's actually a funny story behind the implementation of this. I actually wasn't going to add it to Mapbase, but when I was gleaning Insolence's repo for their projected textures (with permission) I was just copying and pasting code and nesting it in "ASW_PROJECTED_TEXTURES" and because they make changes to the same places I assumed the "ShadowFromWorldLights" stuff was part of the projected textures. I realized what I was doing eventually, but I still basically implemented dynamic RTT shadow angles by accident.
