3D developer E-on Software has announced Ozone 2.0, its updated atmospheric creator plug-in for LightWave 3D for both Macintosh and Windows. New features in Ozone 2.0 include a volumetric atmosphere system that simulates the interaction of light and air as light travels through the atmosphere, the ability to animate clouds and sun to create realistic skies and improved rendering technology. Ozone 2.0 ships with over 100 predefined atmospheres including bright daytime, bad weather, sunrise and night-time with the ability to combine atmospheres to create custom effects. Ozone 2.0 will be released at the Siggraph 2002 conference and exhibition in San Antonio, and will ship at an expected street price of $249 (£170).
