# init(castsShadow:receivesShadow:) Creates a grounding shadow component by configuring whether its entity receives shadows from other model entities with the component. ``` init(castsShadow: Bool, receivesShadow: Bool) ``` ## Parameters `castsShadow` A Boolean value that indicates whether the component’s entity casts a shadow on the environment and other model entities. `receivesShadow` A Boolean value that indicates whether the component’s entity receives shadows from other model entities. ## Discussion This initializer is an alternative to [`init(castsShadow:)`](/documentation/RealityKit/GroundingShadowComponent/init(castsShadow:)), which creates a component that, by default, configures an entity to receive grounding shadows from other model entities in the scene. --- Copyright © 2026 Apple Inc.
