### Example: Invert Value


This example shows how the **Invert value** option can be used to push all colors in the **Reflect IOR** render element into the 0.0-1.0 range, and also how to determine the IOR values right within the [V-Ray Frame Buffer](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111739034). In each image, the values are sampled using the **VFB Toolbar**.
