View Full Version : Spinning Lights?

I have recently been hired on by a company that uses 3DS, However I have always used LightWave for all of my work. I feel I have a pretty good handle on Max however I really miss a trick LightWavers used to use to simulate the diffuse lighting that you would get by using Global Illumination. The method was to take a point light or set of lights and parent them to a dummy object in your scene and then spin the dummy object over one frame. So on frame 0 you would have your lights in the position you started from and at frame 1 you would have them at the same position but between the two frames they would have spun around the scene 720 degrees. I would then set motion blur to be Dithered and to %50. You then tell the lights to repeat over the duration of your scene so they keep spinning. Spinning these gives the lights a radiosity affect, and it gives off a wonderful diffuse lighting with nice soft raytraced shadows, and at a fraction of the render time!. I have tried to simulate this in Max but with no success. Any help that could be provided would be very much appreciated. Thanks a lot!

Hey Paul K,

I was so jealous when I found out that Lightwave was capable of doing this nifty little trick. While working on a series as a lighter, a spent about a week trying to figure out how this idea could be replicated in Max. After asking others, and playing around with various ideas I couldn't find a way to mimic this trick in Max. If your looking for a way to get some nice renders without the use of those time-intensive renderers, you may want to look at something like a domelight script. These will basically mimic a skylight and give you some nice lighting with very reasonable render times. Check out Scriptspot (http://www.scriptspot.com) for lighting scripts. You should b e able to find what I suggested there. Good luck! :)

i think* you need to attach a light to a spline and have it follow it along the path of the spline. i've never done it, but i'm pretty sure i've read tutorials or threads about that in 3ds max.





*i think, therefore, i'm not sure

Create a sky light then go into the rendering menu, select advanced lighting, and turn it to on. Not sure if this is what your trying to do though.

heya-

at that time I was lighting for a television series which at the time called for some pretty realistic lighting for some some sets, and some really "bizarre" lighting for other sets. I found for the realism look the skydome or skylight script worked really well. The script in particluar was written by Andy Murdock of L.O.R. (http://www.lotsofrobots.com) fame. You might be able to still find it on his site. If not just let me know and I can email it to you; I hope he doesn't mind. :)

I have used this technique on everything from television series work, to commercials, product shots etc.; it really works. And when using this technique in conjunction with a levels filter in Photoshop or any compositing software you can make any image look pretty sweet. :)

I did that with max.

I created a light and animated it over
10 frames. I moved the key on frame
10 to frame 1. My light takes only
1 frame to move around the scene
360 degrees.

I then set the rendering to do
motion blur and set it to render
multiple frames for each image.
It would render the light in each
of the positions at each of the
fractional frame positions.

Worked fine. Takes less memory
than multiple lights but
longer to render
