Ultra Dynamic Sky

Version 9.5 adds a Voxel Clouds sky mode that renders the volumetric cloud layer as hard cubic voxels for stylized and voxel-art scenes, plus a Niagara freezing-breath effect driven by temperature, stars that drift with time of day, and 7.1 spatialized weather audio. It supports Unreal Engine 5.5 through 5.7.
