SkyCard v4.21+ is a high-quality collection of 2D impostor clouds designed for Unreal Engine 4. These clouds create the illusion of volumetric objects through high-quality self-shadows, without using normal maps. They dynamically respond to changing sunlight directions and offer adjustable parameters such as density, shadow blur, and light/ground scattering, making them highly flexible for various environments and compatible with any HDR background. With SkyCard, developers can create a wide range of skies—from realistic storms to stylized cirrus wisps—offering both artistic and technical versatility.
