**Recursive Rendering** Indicates whether to include this material in the [recursive rendering pipeline](../../../Ray-Tracing-Recursive-Rendering.md). When enabled, if your project supports [ray tracing](../../../Ray-Tracing-Getting-Started.md) and a [Recursive Rendering](../../../Ray-Tracing-Recursive-Rendering.md) Volume Profile override is active, HDRP uses ray tracing to render this material.
