Faking Radiosity???

[Capel]

Is there a way to fake radiosity/dome lighting setup? I really need to cut down on some render time! Any ideas? Thanks in advance!

What I would do is use luxigons and duplicate spotlights for each polygon.

If this makes no sense check it out under newtek's tutorial section for LW about Luxigons. Very Easy.

This should do the trick.

I know what you're refering to when you meantion Luxigons, but I don't know how to do this and I looked under NewTek's tutorials. :confused:

It's the rotate'n lights trick coupled with motion blur.

You parent some lights to a null at diffrent angles. Spin the parent null 720 degrees or so over one frame. Go into the Graph editor and Select the Null and repeat is rotation... Put a distance light under everthing to emulate bounced light- exclude the floor if you have one in your scene. Turn on Raytraced shadows if you're using a light that needs it.


Hit f9 and bada boom bada bing- cheap fake'oid radiosity.

Which kind of light you use and how many of them is up to you as it depends on the scene and what's in it. I like shadow maped spot lights with big old fuzzy shadow maps and/or Area lights...

I've included a lame'o scene showing the basic "spin trick" using Area lights...search for more tutorials as they are EVERYWHERE.

Also look into using HDRI lighting, motion blur, and low ray radiosity to get some good resaults fast...

Somebody pointed me to this and it's great!

Using a Spotlight instead of area light if you want a spinning light trick.

This should get you started:

It's a commercial script collection, but you can use it for free (it just has some nagging screens).
