### Remarks

LOD culling is enabled by using [RayTracingInstanceCullingFlags.EnableLODCulling](/engine/6000.7/script-reference/unityengine/rendering/raytracinginstancecullingflags/enablelodculling.md) flag in [RayTracingInstanceCullingConfig.flags](/engine/6000.7/script-reference/unityengine/rendering/raytracinginstancecullingconfig/flags.md). If the flag is not used then all the Renderers in the [LODGroup](/engine/6000.7/script-reference/unityengine/lodgroup.md) will be processes and eventually added to the acceleration structure.
