I haven't played with lighting much... anyone have any thoughts on doing something like this?

If the API can tie into the waypoint system from Rugged Reroll there might be a possibility of doing something like this as far as the bread crumbs are concerned by creating a light generating token at each waypoint. I have no idea if directional lighting is a thing though.

I saw this in the wiki.... it's what got me thinking... Light scatter close to a bulls-eye lantern and its focused directional light... (two clear items to create that effect.) light_angle "360" Angle (in degrees) of the light's angle. For example, "180" means the light would show only for the front "half" of the "field of vision". light_losangle "360" Angle (in degrees) of the field of vision of the graphic (assuming that light_hassight is set to true)
