Rendering a realistic car

[meatlockerii]

hi,

I'm planning on modelling a realistic car. Once i've completed the model i'm considering compositing it into a real scene (i.e. live footage or a photograph).
If i'm going to composit it into live footage and i want it to go down a street what special maps would i need e.g. a reflection map of the suroundings, and what would be the best way to get these?

thx.

make sure you tinker with fresnel falloff.
i think its called incidence something in xsi.
the priciple is just to make sure the surface isnt uniformly reflective.
incidence will enable you to make surfaces approaching parallel 100% reflective and then reduce quickly as they approach perpendicular.

Add sticky finger prints!
Im sure going to.

You need good reflection maps.

Or you might want HDR reflection maps. These are images with whites brighter than 1, so that the sky and light sources appear very bright.

mm indeed.....
it looks like with all the reflection advise, you should be spending a significant amout of time preparing your environment, be it modeled or painted...
