This page provides information about the Lens Effects in V-Ray for Nuke.


## **Overview**

---

V-Ray Lens Effects simulates real-world camera lens effects such as bloom and glare. The plug-in uses a fast multi-threaded technique to compute the result and provide an immediate update.

V-Ray Lens Effects are applied in the RGB channel together with other post effects. When either a Denoiser render element is used or Source LightMix or Composite mode, then the lens effects are applied to the effectsResult channel.

The Lens Effects layer is accessible from the **V-Ray** menu > **Renderer** > **VRayLensEffect**. 

A freeware Nuke plugin that implements the V-Ray Lens Effects as a Nuke node is available for [download here](https://drive.google.com/drive/folders/1qXN83NHj05b2VTpFcoOSX4uOcfsfQU9O?usp=drive_link). 

> ℹ️ The VRayLensEffects plugin is now built on the OpenFX standard, ensuring universal compatibility across all versions of Nuke.  
> ℹ️ After downloading the .zip archive, check the included **readme.txt** file for more information.
