What is VBD, you may ask? VBD stands for Volumetric Breakdown, a new feature in Unreal Engine 5.3 that allows you to create realistic and dynamic volumetric effects such as smoke, fire, clouds, and fog. VBD uses a novel rendering technique that simulates the scattering and absorption of light by participating media. You can use VBD to enhance the atmosphere and realism of your scenes, as well as create stunning visual effects for your games and projects.
I hope you enjoyed this brief introduction to VBD and Unreal Engine 5.3.
