OFDR Lighting Weather Physics HDR Upgrade 2017 file

Physics and Visual Effects Upgrade
Modifies the special effects used by the engine for impact and explosion effects of different ammunition versus different materials. Explosives churn up much more dirt, set things on fire and cause billowing smoke to fill the scene.
Each explosive ordnance type now has 8 individual material effects instead of just 1!
Each material type has also been adjusted to give more realistic vehicle wheel friction and better bullet penetration.

Weather, Lighting and HDR Upgrade
Improves the sun/moon transitions and changes sunset and sunrise to real-world times for much better day/night cycles.
Fog system reworked to give greater weather variation in the form of thicker, darker clouds, closer fog and darker night times.
Something unique to Island War is my custom eye adaptation simulation via the HDR system. What this does is adjust the way the image is rendered according to how much light is hitting your virtual eyes.
This allows you to see in the dark, but also means anything bright will blind you and ruin your night vision (lights, torches, explosions and muzzle flashes as well as using thermal/night vision for extended periods)
Looking into a building during the day will look very dark, while from the inside it will be nice and bright, with outside being blinding to the eye.
