The Irradiance map viewer can be used to view, merge and save light map files created by V-Ray. It works with Irradiance maps and Light Cache maps.

 

Overview

The Irradiance Map viewer tool allows you to navigate around a 3d projected version of a scene to view where GI samples were taken during the rendering process.

Note: The viewer is a separate program and does not require the V-Ray host application (3ds Max, Maya, MODO, etc.) to be running.
