Hi all,
I'd like to create some glowing electronic billboards in my scene, billboards that  produce their own light and affecting the objects nearby...but cant find the way that looks good....if anybody knows how to do it and post here it'd be wonderfull :)
Thanx...

Simple, you can make the Luminous and render in GR, the more luminous they are the more light you will get onto your scene...or you can fake it with area lights(;

Wow, thanx for fast response Trepz, gonna try it now...

good luck with it (;

Create an area light (Infinite only)

Looks great, unfortunatelly I got only esprit.....maybe Light module helps..???

Yeah, it has, i just thought that youre - Infinite only - means that theres something more to areas lights in Vue....

Sure I am an Infinite user, but I think I can’t live without the advanced light settings. It helps me a lot.

If you only want the material to seem iluminated (and not really cast light), luminosity is the way to go, IMO. From my personal experience, I found that area lights are slower to render and introduce noise. Of course, if you really want the billboard to cast light to visibly influence other elements in the scene, then you should use area light.

Yeah, I tried both...so far area lights look too grainy and not as i expected.. No matter how strong it is i doesnt  affect nearby  objects  too much...but I dont give up :)

You could also simulate an area light using this simple method (I used this somewhere, cant remember where).  For example, create a cylinder and make it only slightly transparent (5%, for example). Evenly spread inside the cylinder several point lights. The cylinder will appear to glow and will efectively cast light to the neighbouring objects. If you want a very uniform light, use more point lights or make it really very slightly transparent and increase the light power. Try various combinations of transparency and power of the lights until you get the desired effect.

Yeah, this works, but I am trying to do a light ad panel, with mapped picture casting light at nearby passengers....watching too much Blade Runner you know....:)

If you wanna do the panel you really should use GR to render it out...gonna take a month of Sundays for sure, but it is really nice effect(;

You can use the method I suggest and still map any texture you like. Look at my image

This is not a light ad panel but the principle is aproximately the same. I used the sun for this effect but you would use normal point lights.
The one thing that is essential to achieve this result is to increase the "transmited light" (to 100%) in the material properties (I can't open Vue right now so I can't tell you exactly the name of the tab and slider, but this is in the tab where you specify the amount of difuse and ambient light for the material).
If you don't increase the transmitted light, the light will not use the color information of the mapped picture.

Just an additional note:
Of course, if you don't want rays projecting from the material, just do not use volumetric lights.

Thanx all for ideas...
Your way looks most promising Rutra...I think i cant afford GR setup Trepz mentioned on my poor laptop :)
