# Overview

This is a library of production-ready lights for RenderMan, featuring 19 IES profiles.

IES profiles help you achieve physical photometric data distribution, in other words, a realistic light emission pattern based on original manufacturer specifications, giving your art an extra dose of realism.

> ℹ️ For more information about IES profiles, see [CGArena](http://www.cgarena.com/freestuff/tutorials/max/ieslights/).

## How-to

To install in RenderMan's Preset Browser, place the **IES** folder inside your RenderMan Asset Library's **LightRigs** folder. It is recommended that you transfer the installation default RenderManAssetLibrary folder to a non-install location with full writing privileges.

Once you transfer the Materials folder and move your Asset Library into a different location, it is essential to tell Maya through the preferences that you want to use the new path.

Or you can create a new environment variable in your Maya.env file like so:

`RMAN_ASSET_LIBRARY = /My/Folder/Example/RenderManAssetLibrary`

This will make sure you are always pointing to the correct folder.
