Did a bit of looking and couldn't find a thread on this topic. I'm working on a game which will require players to constantly put on and take off masks and helmets (limiting field of view), switch flashlights on and off (Major penalties to stealth with a light on, obviously), and may include the use of multiple different light sources (One person carrying a lantern that casts light in a circle around them, versus switching on the weapon light for fighting that casts a narrow cone of light straight ahead, versus pulling out a very small, weak light source if another goes dead or gets broken). Doing this how I want it presently will require that I be constantly adjusting player vision and light. Doing this requires two things: 1) The ability to toggle light or vision sources on and off via macro buttons available to the players. 2) The ability to set up different light sources that can be switched between using these buttons. This also would handle some aspects of things such as darkvision and low light vision. Simply set improved vision types as a character light source that isn't viewable by other players. The ability to name these light sources would also be handy. I think this would be easily handled by adding the option to add additional light/vision modifiers, and a simple button to check/uncheck the "use" box for each. Treat the top light source and vision cone as the character's default, to which they return when they remove or switch off any lights or vision-modifying things. I also had thoughts on player placed light sources (putting down a flashlight, throwing a torch, etc), but this can generally be handled by the GM in all but extreme circumstances.
