View Full Version : lightening question...

how do i make the object glow ?
i don't mean the "simple" glow feature... i saw a lot of images , where the object itself has light.. like a text logo, everything is black except there is a light cimmong out of the logo....
how do i make this ?

this quite simple. check the surface settings, there is a parameter called luminosity. this will make the object emit light. if you use now some glow or bloom (plugin) you will get this typical glowing appearance. maybe add some fog or other volumetric effect to enhance the 3d feeling. hope this will help.

Yup Yup... Luminosity is what you need in the surface editor... also... you need to render with radiosity for it to actually effect other surfaces. Here is a test render I did.... only light is from the underside of the text.

Beautifull image minus, but during a prod you simply fake the luminous with luminous maps. Render a zillion time faster.

Thanks Facial, it's tips like that what make me love this place lots :D
It's my first post on this list so, Hello everybody ! :wavey:
As Facial Deluxe said, luminous maps are the answer, but you
can made then with the surface baker to keep the radiosity feeling.

Can someone explain these luminosity maps please? Radiosity takes forever to render and I intend on using some glowing objects in an animation I am working on.

Noone can explain to me what luminosity maps are or how to make them? :surprised

just put an image map in the luminosity channel, and voila!The image need to be grayscale, where pure white means 100% lum, and pure black 0%
you can achieve great effects with image-maps... just try it!

oh, i thought they were talking about something fancier than just an image map in the luminous channel. :rolleyes:

Here is another scene I did only using surface lighting... actually in this one though there is also a bit of ambient lighting too.
Please excuse the poopy jpeg compression.
