This page provides information on the V-Ray IES Light.

Overview

Photometric lights utilize an .ies file that contains the distribution profile for the light. An .ies file contains complete specifications of a real-world light bulb or tube including the shape of the light cone and the steepness of the falloff of the light. Such files are usually provided by the manufacturer of the real-world bulb, and the information in those files, which is gathered through lab experiments, is extremely accurate in its representation of the light source. By loading an .ies file, the properties of the light are recreated within Rhino and used by V-Ray during rendering.

IES lights are particularly useful for architectural interior renderings, where it can be important to show the actual result of using specific man-made light sources in the scene.

V-Ray IES light(s) can be instanced by using Array or Alt+drag the light object in the Rhino viewport.

Parameters

Enabled () – Turns the VRayLight on and off.

Color – Specifies the color of the light.

Intensity (lm) – When enabled, specifies the strength of the light in Lumens to override the intensity specified in the .ies file. See Intensity example below for illustration.

IES Light File – Specifies an .ies file to use for the current light.

Shape – Determines the shape of the light when calculating Soft Shadows. By default, VRayLightIES uses the shape information stored in the .ies file. See Shape example below for illustration.

From IES File - Uses the shape information stored in the .ies file.
Point - Treats the light shape as a point light.
Circle - Treats the light shape as a planar circular area light. Its dimensions can be specified with the diameter parameter below.
Sphere - Treats the light shape as a sphere light. Its dimensions can be specified with the diameter parameter below.

Diameter – Specifies the diameter for applicable light shape types.

The Diameter parameter is only available when the Circle and Sphere shapes are selected.

Options

Shadows – When enabled (default), the light casts shadows. When disabled, the light does not cast shadows.

Affect Diffuse – When enabled, the light affects the diffuse properties of the materials.

Affect Specular – When enabled, the light affects the specular of the materials.

Caustic Subdivs – Used by V-Ray when calculating Caustics. Lower values produce noisy results but render faster. Higher values produce smoother results but take more time.

Example: Intensity

This example shows how the Intensity parameter affects the IES light.

Example: Shape

This example shows how light is affected by the different shapes of the IES Light. Circle and Sphere shapes examples are also compared with different diameters - 1.0 and 10.0.

Notes

Light Color and Intensity may also be adjusted in the Rhino Light Property Panel. If the intensity is set to 0, the value from the .ies file will be used instead.

Jürgen Furrer has launched IES Library, a new online library of IES files for use in architctural visualisation and illustration work.

The site currently has over 90,000 IES files available to download for free, representing real-world lights from manufacturers like GE, Osram and Philips, each with a rendered preview of the light pattern it generates.

Download IES files for real-world light fixtures for use in DCC and CAD software
A global standard for photometric data, the IES file format encodes the intensity and spatial distribution of light emitted by real-world light fixtures.

IES files are supported by most industrial design and visualisation software, including DCC applications like 3ds Max, Blender and Maya, either natively or through renderers like V-Ray and Arnold.

Although IES files are freely available online, IES Library collects together data from many individual repositories, including those for a range of major lighting manufactuers, and eliminates duplicate records.

Each file is presented with supporting information like wattage and bulb type, plus a standard render showing the lighting pattern it represents, generated automatically in Blender.

Files can be filtered by manufacturer or by type: there are simple categories for downlights, uplights, flood lights and multi rays.

New tagging and browsing features planned for the site
Furrer is currently in the process of populating the library with data, and says that he has around 160,000 files to process in total.

Future features planned for the site include a contextual tagging system, the option for usrs to rate individual files, and a Blender plugin to make it possible to browse files directly inside the software.
