LCD glow

[circus]

Can anyone give me a few tips on how to make a realistic colour LCD (ie a tv or new moblie phone)

I used to just add extra light to a bitmap (avi and jpg) when i used Max's scanline, but now that vray gives me more realism it just doesnt look right...

Thanks.

Give me some more details on what you are trying to do. If you want to make this fade effect which takes place when you watch a LCD screen form angle, then some falloff map should do the trick. To add glow just go to rendering>effects>add>lens effects>glow and assign it to material id in "glow element">options. Or maybe you want to make the material more luminous? Well, I use brazil usually, so I'm not quite into the depths of V-Ray but there has to be some energy contorlling option. You may just adjust the exposure of the image.

use the vraymtlwrapper, under base set the type to standard, use the self illum slot in your standard material to create your lcd colour, back up to the material root and use the generate gi to create the glow/illumination - (but not glow like the lens fx) have a play

thanks for your help, I have used glow in the past but VRay seems to have its own issues with glow...

However the glow is limited to one colour...the effect im trying to get is silimilar to the way a HDRI lights a scene - ie the colour of the pixel in the bitmap dictates the colour of the lcd screen glow...

any ideas?

render the selfilluminated section on its own and comp it in photoshop using a little blur and screen mapping and a little transparency and you should be fine.
