## **Notes**

---

- The **Reflective Caustics** and **Refractive Caustics** options of the [GI section](https://docs-chaos.atlassian.net/wiki/spaces/VRAYHOUDINI/pages/113279796) in the Render Settings cause a similar effect to the final rendering, but these caustics do not show up in the Caustics Render Element.
