## **Usage Notes**

The **Raw Refraction Filter** Render Element is useful when a precise mask is needed for refractive objects. Unlike the [Refraction Filter Render Element](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575265), there is no need to clip or readjust values when pure black or white is required for the composite.
