Shading Question

[amitc]

Guys,

I have somewhat interesting shading question.

I have a scene with simple building and I have a particle around the building in some fashion.
Here is a link to the picture .
The picture contains a vector an texture rendering of the building.

What I want to do is shade the building with each particle's color near its region.
For the in between areas the colors are interpolated. So its some sort of smooth shading.

The particles color is changing with time.

How do I accomplish this?

Do I combine the the building elements into one object and do some sort of ramp shading?
But it needs to be precisely driven by particle color in each region.

Tips and pointers appreciated.
Thanks

just a wild idea,
maybe you can render a reflection pass of the particles
on the building,blur it and matte it in comp.....

Hi,
Maybe you can attach a colored omni light (with decay) to each particle (there's even MEL scripts on this site to do that automatically ) . It may produce the effect you're looking for ...

Guys I am a little off here.

MJblack can you elaborate a bit more. How do I make reflection of particle color show up on the building?
Would that mean create a higly reflective shader for all the building object?

guy_iti interesting thought, I could not find the mel script you were mentioning would you mind pointing me to it. The challenge here would be to figure out decay for every light so they do not cause interference beyond their zones

What I want is the whole building colored by particle systems color. So no texture, etc on the building..

Thanks

Found it :

As for the decay, indeed you 'll have a bit of calculations to do ... but you only have the choice between linear, quadratic and cubic.

Good lcuk,
Guyb.

Thanks guy_iti. It'll need some work for the experiment.
