Description:

This tool allows users to place and hand sculpt volumetric effects in their world. It is useful for not only providing amazing natural fog effects but useful as a full blown volumetric pipeline able to replace many traditional vfx such as candle smoke, waterfall mist, sandstorm vfx, and more! The tool also provides the ability for landscape conforming fog, and mid air light rays not cast by shadow casters. All of the Volumetric features in this pack are also setup to transition naturally by time of day, allowing users to get natural thicker fog along the grounds at night/morning while transitioning into a softer fog or no fog during the day. Time of day features work directly with the ground conforming tools, on a per fog actor basis, and built in ambient fog settings.

Features:

• Hand place fully customizable volumetric points

• Full gameplay implementation, full 3D player paths, bullets create paths, grenades clear fog etc...

• Each fog point has full frustum, distance, and occlusion culling.

• Overlap and stack fog points as much as you want with literally zero overdraw.

• Does NOT require distance fields to work, just enable volumetric fog and your good to go!

• Mix and match 4 unique fog noise values together to blend and sculpt each fog point uniquely

• All fog self shadows in the direction of the sun, values fully adjustable

• Landscape conforming fog with day/night adjustable heights/densities

• Fully adjustable mid air light rays (Without shadow casting objects)

• Full time of day support for transitioning values (Dense fog at night, no/less fog in day, height values, etc.)

• Sphere fog points provide infinite distance representations so fog can render at any distance.

• Fog gives artists full control over color, self shadowing color, wind direction, fog scale, time of day values, and more.

• No size limitations to how large or small fog points can be.

• Multiple fog shapes from cubes, rectangles, spheres, capsules

• All fog points can be cut in half with adjustable heights and billowing along cut edges.

• All fog points allow fully unique wind speed/directions and fog noise shape/scales, mix and match at no extra cost.

• Use fog points to remove fog inside interior spaces such as buildings/caves.

• Fog points have vortex wind mode for allowing shapes to spin tornado style.
