During 2020, I worked on a research project for Milestone, the biggest videogame company in Italy.
They wanted me to develop a system for real-time rendering and authoring of volumetric clouds, integrated in Unreal Engine 4. Without furher ado, this is the final video showing-off the visual features (it has a slow pace since it was supposed te be played as a during my oral presentation).
It has been a long project and I’ll sum up here the main challanges. Not far from the following references.
