Volumetric Storm Clouds

I developed a real-time volumetric cloud system in Unreal Engine to create dynamic and atmospheric skies for my capstone project. The clouds use flowmaps and volume textures to create the shape of the clouds. Additionally a hemisphere mesh with an animated material is used to represent the center of the storm. I also worked on optimizing the volumetric clouds so they can run real time in a video game level
