Virtualight is a new, free
rendering tool. It supports radiosity, caustics and sky sphere lighting. It is a
"global illumination renderer".
There are a lot of people learning it right now and some of them participate
in the news-group at
news://news.3dvf.net/Virtualight_US The author of the software,
Stéphane Marty, is very actively involved in helping and answering questions.
Give it a try.
|The first conversion was done from the 3DS-file
with the included conversion tool "3ds2vib.exe". The rendering was tweaked
in the source-files to include a sky and an area-light and some materials
were edited. This was done based on the included examples.
still needs a lot of tweaking... I edited the textures out, because they
turned up black with the initial conversion.
||Then I used the script for 3ds max (v4 only!) by theGuzz, which can be

should see a familiar building ;) The script is now included in the normal
|After running the initial script once, you have an area light-gizmo
and a Virtualight-base-material available.|
|After setting camera and the lights and textures, you can add the
VirtualGUI-rendering effect and let that one take over the rendering.|
|I loaded the ArchiCAD-exported 3DS-file
into max4, changed all the textures to TGA and could begin rendering.|
|I used the example glass-settings from theGuzz's site and added an
area-light on the place where my sun-spot was located.|
|I deleted the rest of the lights and used a "sky" and turned global
|No sun was used.|
After some trying and missing, I got some good renderings. There's still
an artifact near the top windows that I haven't figured out yet!
Vlight vlight -f -o simple -r 800 600
Total computing time: 501 seconds (more than 8 minutes)
Vlight vlight -d -a 2 -e 0.25 -g 0 -f -o better -r 800 600.0
Total computing time: 4989 seconds (more than 83 minutes and I still have
the artifact very visible...)
Peter Lammers made this next rendering for the Virtualight-newsgroup.
This gives the scene a whole different atmosphere. I like it.

Alistair Dickinson did this rendering for the Virtualight-newsgroup. He
changed a few settings and worked on the 3DS-model
in MAX, to get rid of some geometry-problems from the 3DS-export from
ArchiCAD. He used skylight along with the spotlight I had set up in the 3ds
"I changed all the object names in Max and most of the material names. I
left most of the materials untouched in Max except for the grass, I
tweaked the map in photoshop to add a bit of brown and set Kd to 0.7
once in VLight. The Kd for the concrete was set to 0.65."

|very complete rendering possibilities (including area-lights, radiosity,

|Editable (well, it feels like programming)|
|Somehow still difficult to use but the progress with the plugins is very
promising. And you can still edit the code if you need to.|
