3d Max Vray Ies Light Download. By thylsflexusach1978 Follow Public. In this scene we're going to demonstrate the IES lights effect, using a basic scene and Vray IES lights, you can download a lot of free IES file from the web, just google it. Jan 8, 2018 - This pack includes 1600 unique IES files from German lighting manufacturer Erco.Use. By loading an.ies file, the light's properties are recreated within 3ds Max 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. While 3ds Max has standard photometric lights, V-Ray.
This lesson gives a basic sample lesson plan for introducing the V-Ray IES Light.
Lecture
- Unless you’ve already covered this part in another lecture it may be useful to establish certain qualities that all real-world lights posses
- Talking about decay (a.k.a. falloff) is important. As an object gets closer to a light source, its lighting exponentially increases in brightness. (Inverse Square Law)
- Color and temperature are an important point to touch on with real lights, and how temperature usually defines the color of a light
- Larger light sources usually create more light and softer shadows than smaller lights with the same intensity
- Since IES lights are all about simulating real architectural light profiles, show some images of light fixtures and the lights they cast to show how different lights have different properties that are defined by their fixture and bulb and lens, etc. This will make it easier to explain that IES lights try to simulate these lights and how they really look.
- The major settings of the V-Ray IES Light are quire straight forward to explain.
- The color mode allows us to have flexibility when setting up the light color. You can either use precisely measured colors using the Temperature mode or just pick a color you like.
- It’s important to note that the IES file holds information about the intensity of the actual light source but that can be overridden
- Like with the standard V-Ray Light the V-Ray IES Light has controls over which parts of the image to affect. You may choose to explain those or point the students to the lesson about the V-Ray Light
- The softness of shadows also depends on the IES profile but can be overridden
Demonstration
- In this cycle, you are going to demonstrate the options of the V-Ray IES Light. You can use either the provided scene and handout or create your own.
Activity
- In this cycle, you are going to let your students experiment with the provided scene. You may want to give them the provided handout to use as a guideline.
Available materials
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.
Users have suggested making it possible to filter data by the type of fixture in which a light can be mounted.
Availability and system requirements
The IES files on IES Library are free to download, and are licensed for commercial use.
