Very easy to setup ! Tutorial here: Youtube Tutorial
There is also an "inverse feature", which allows you to disable shadow casting on the linked lights when the player is inside the region. This is extremely useful when you want to optimize a multi floor room for example.
You can have the lights on your floor casting shadows, and all the others ones with shadow casting disabled.
Depending on the number of lights affected, you can expect from 20 to 50% performance improvement in the rooms where you will use this system, making them playable on low end gaming computers (8 years old i7 950 processor and GTX 950 graphic card).
All that in "Epic" settings for everything except shadow (high)!
If you use dynamic lighting, You can get an even better performance boost when used with our Dynamic Lighting Portal System plugin
