Bladerunner screen effect, city lights?

[camfran]

Hi clever people,

 

I want to make the effect of a large tv wall at day and night, like the massive ones in Bladerunner. It doesn't have to be animated as it's for a still rendering.

 

I don't really know where to begin to make an image that shines! It's to go on the tower bit with a picture of a sail boat on it at the moment.

 

Also do any of you know how to make the effect of buildings with lights on randomly, preferably as a material which can then be applied to a box building to give the impression of an inhabited city at night?

 

Thanks!

Start with a perfect hires texturemap, than create the proper material. For a big screen(wall) you need the cool scanlines, there are some tuts for that on teamphotoshop.com or follow the few steps here:

 

- load your main picture (what will be your screen)

- new layer and draw horizontal lines 2 to 4 pixels width, transparency in between

- set the new layer to overlay or soft light

 

This trick will create cool scanline effects. Your material should be a middle glossy with high specular, maybe some glossy control applied on the refl. settings.

 

Start from here and experiment further with it, you'll get a cool screenwall in no time.

 

Regards,

Dennis

Great thanks i'll try that to make the image.

 

Does the material have to become self-illuminated or something for it to 'glow' at night? What kind of settings would that need in vray?

 

Many thanks.

If you use a standard material self illumination is good. If you use a fancy mat like vray or brazil, then go for the lightmats with your screentexture applied. But i thyink a standard with 100% selfillumination is great. You can experiment with an omni in fornt of your screen, lighting up only your screen in the include/exclude settings of the omni.

I think i get better results with the vray light material -- more contrasty than the flatter standard with self illumination, no matter what i play with on the standard material's settings. Shame there's not more control on the VrayLightMtl setting -- just the multiplier. You can't even do a percentage of the texmap to apply.

 

See below for comparison...

 

Also, any ideas about the city lights idea?

 

Thanks a lot

For the city light you could try a load (100+) little spheres with a strong vrlightmat applied, or a similar count of plain omni's...

you can even try to put out your desired image on a tv and then photograph it from there. you will get a perfect "screen-looking" image.

you can also try it with a standard-monitor. for my purpose i did it with my notebook-screen. but i had to scale the image down quite a lot and photograph it in macro-mode to get the desired "pixel-effect", you can see my resulting texture here. i applied it to a standard-material with selfillumination and got pretty decent results.

Cool yes that looks like a good easy way to get the squares effect, and some more low-res impression!

 

Nice one, thanks

I used to use RetroScan by Deep Devices for creating TV screen effects on images, but I think it is Mac only.

 

I haven't tried this one yet, but it looks like it might do the job for the image processing part.

...i am sure there are more of these out there also.
