DCS is getting new Fog and Dust Systems niiiice!
The next update will feature substantial enhancements to DCS weather in particular a new state-of-the art fog and dust rendering system. This highly immersive solution, which took more than 8’500 man hours to develop, allows both automatic and manual fog generation and accounts for sensor and AI line-of-sight blocking. It is calculated with our future spherical Earth in mind and can be highly variable based on density and altitude. It supports self-shadowing, blends with clouds, and is fully animated with moving cloud banks.
Scenes from the early morning and evening hours are particularly convincing and offer a surprisingly realistic atmosphere.
The New Fog Despite all the development challenges, we managed to find a truly state-of-the-art solution, and all the aforementioned problems have been resolved.
● Implements a new fog reconstruction previously undocumented on the internet.
● Is fully compatible with cloud shading and is an integral part of it.
● Is calculated on a spherical Earth.
● fog quality that is virtually identical and stable.
● Can be extremely dense and very low.
● Receives shadows from clouds and the ground.
● Accounts for self-shadowing.
● Blends with clouds.
● Can have any color and correctly blends with clouds.
● Is fully compatible with the rain volume.
● Can be inhomogeneous.
● Can be animated, and we've implemented this capability.
● Has a maximum thickness of 5 km and can be used to simulate airborne particulates.
The dust effect is now also implemented based on the new fog and is fully compatible with shading. Like fog, the dust effect now affects sensor visibility, which wasn't the case in previous versions of DCS. In the Mission Editor's weather interface, you can set fog animation or choose the auto mode. Currently, in automatic mode, fog appears at sunset and dissipates after sunrise. This mode will be significantly developed in the future to consider weather conditions, precipitation, cloud density, temperature, humidity, etc. This is just the beginning. We've also added a fog scripting API, which allows you to animate the fog in any way and tie it to events. All of this synchronizes over the network, enabling fog animation to be part of network missions.
Volumetric Lights
Light scattering is one of the key features of clouds and fog, creating a glow effect around light sources. We've also advanced in this direction and have now added support for volumetric light sources. Fog and clouds are now illuminated by various light sources depending on their density. Moreover, clouds and fog now receive and scatter light from the ground. You can notice how clouds and fog are illuminated by city lights, making night lighting look even more realistic.
