Shadows are a vital part of making an environment feel ‘alive’, and trueSKY supports realtime shadows on all clouds, based on the position of the sun/moon.
In unreal, shadows should automatically be set up. If not, make sure that the CloudShadowRT is connected to trueSKYObject under shadows, and your directional light is using trueSKY’s M_lightFunction.
