Fog, smoke, fire, and other physically-based visual effects rendered by a real-time engine.
Atmospheric is a term used in virtual production to describe the simulated Fog, smoke, fire, and other physically-based visual effects rendered by a real-time engine. It is an essential part of creating realistic, immersive scenes for movies, TV shows, video games, and even live performances.
Atmospheric effects can range from small details like lightning flashes or distant thunder to more dramatic large-scale changes such as turbulent clouds rolling over a landscape. There are numerous types of atmospheres that can be created with computer-generated imagery (CGI), including rain, snow, dust storms, and fog. These effects can also be achieved using practical elements like fans, pyrotechnics, and wind machines.
This type of atmosphere adds depth and dimension to shots, helps set the tone and mood, and allows viewers to feel immersed in the scene. Additionally, atmospheric effects can add realism to special effects sequences, helping create tension, excitement, and mystery. Atmosphere has become increasingly important in recent years as filmmakers strive to make their stories look as realistic as possible while still being creative.
By combining CGI and practical elements, filmmakers have been able to create stunning visuals that bring their projects to life on screen. From blockbuster films like Avatar to smaller independent productions, atmospheric effects are essential for creating believable worlds.
