# Objective - Improve ergonomics / documentation of cascaded shadow maps - Allow for the customization of the nearest shadowing distance. - Fixes #7393 - Fixes #7362 ## Solution - Introduce `CascadeShadowConfigBuilder` - Tweak various example cascade settings for better quality. --- ## Changelog - Made examples look nicer under cascaded shadow maps. - Introduce `CascadeShadowConfigBuilder` to help with creating `CascadeShadowConfig` ## Migration Guide - Configure settings for cascaded shadow maps for directional lights using the newly introduced `CascadeShadowConfigBuilder`.
