A Unity Extension for terrain occlusion through entity revealed global fog. Supports permanent revealing and an option to save and load its state (alpha).
It's pretty simple:
Drop the FogOfWarInfluence Component onto entities that should reveal fog and configure their radius.
FogOfWarSystem is the main Component, where the basic settings can be configured.
Size determines the area of fog (see editor gizmo as an indicator).
There are two modes of rendering: DirectSeeThrough and Projector. DirectSeeThrough is a little trick to save performance, Projector is the little less performant, but more accurate option. Just play with them to see their visual difference. Details for the rest of the settings can be found in their tooltips.
