| [projectionType](/engine/6000.7/script-reference/unityengine/rendering/lightshadowcastercullinginfo/projectiontype.md)         | The projection type of the shadow-casting light to be rendered. For example, directional light shadow-maps will have orthographic projection. Spot lights will usually have perspective projection, but you might want to implement orthographically-projected box-shaped spot lights in your scriptable renderer pipeline. |
| [splitExclusionMask](/engine/6000.7/script-reference/unityengine/rendering/lightshadowcastercullinginfo/splitexclusionmask.md) | A bitmask that represents the shadow splits in [LightShadowCasterCullingInfo.splitRange](/engine/6000.7/script-reference/unityengine/rendering/lightshadowcastercullinginfo/splitrange.md) Unity discards.                                                                                                                  |
| [splitRange](/engine/6000.7/script-reference/unityengine/rendering/lightshadowcastercullinginfo/splitrange.md)                 | The range of [ShadowSplitData](/engine/6000.7/script-reference/unityengine/rendering/shadowsplitdata.md) to use for this light.                                                                                                                                                                                             |
