Here is a question that I see asked often:
We are trying to do a daylight analysis that includes some frosted glass or “kalwall” style skylights which diffuse the light into the space. We can get the VLT (Visible Light Transmittance) values easy enough. However, is there some way to accurately (or semi-accurately) account for the [...]
Manufacturer-based glazing data
Several glass manufacturers provide optical data to the Windows® operating system and Daylight Group of the Lawrence Berkeley National Laboratory (http://windows.lbl.gov).
This group maintains a database and publishes this data via a program called Optics 5. From Optics 5 you can then export a Radiance Material (*.rad file), which can be interpreted
as mental ray [...]
This tool is an assistant which controls the date and time of a Daylight System object for key moments in the year.
It will also control Text objects to display the current Time and Date of the Daylight System:
Here is a video demonstrating its usage:
You can download the tool here.
If you noticed that the location of your Daylight System object created by FBX Import in 3ds Max does not match the project coordinates of Revit, this is a simple thing to fix.
In Revit, go in the 3D view you will export to FBX
Edit the Graphic Display Options
Specify a Location and Time that matches your [...]

HDRI and Photography
With today’s typical hardware, it is not possible to capture a lighting design project in a single shot and get it represented accurately on screen “as-is”. Accurately meaning “how the eye perceived the project at the time the photo was taken”. Typical digital display devices cannot display the [...]
The NASCAR Hal of Fame honors drivers who have shown exceptional skill at NASCAR driving, all-time great crew chiefs and owners, and other major contributors to the sport.
The exterior twisted steel ribbon representing a race track created a potential of glare for pedestrians and cars passing near by. My mandate was to help the design [...]
I am proud to say that the daylight simulation tools in 3ds Max Design 2009 (and beyond) has been validated by the National Research Council of Canada.
I have participated in the process and contributed to the authoring of the following paper: 3ds Max Design Exposure Validation (pdf – 5835Kb) – which describes the process and [...]
MacroScript files for 3ds Max Design 2009 created to improve the workflow of lighting analysis projects.
I will present 2 classes at Autodesk University 2009 .
The first one will be on the topic of Daylight Simulation with 3ds Max Design 2010. The second one will be about strategies to estimate optical characteristics of surface finishes for accurate renderings.
Daylight and Lighting Analysis with Autodesk® 3ds Max® 2010:
How to predict lighting levels in [...]
