## **Render History**

---

The V-Ray VFB keeps a history of previously rendered images, and lists each with a number, thumbnail, and textual details in the Render history panel. Up to four images can be called from the history to be compared in the VFB (as shown below). History files are stored as *.vrimg* files in a user-specified folder. Render history settings can be configured in the [VFB Settings](https://docs-chaos.atlassian.net/wiki/spaces/VSKETCHUP/pages/109791127) window.
