Re: [Tutorial] Making the most of a freebie auto in Poser
-----------------------------------
THINGS TO CONSIDER:


1.) I tend to use raytracing on all metallic and glass parts. This greatly increases the realism of a render; but will also greatly increase the render time. A good compromise is to use a full scene (a room, a skydome, or several props & figures surrounding the vehicle, ... ), and a raytrace node with default settings (maybe .1 for "softness").

However; if the vehicle is in a partial scene, I use a reflection image. I attach a raytrace reflect node to the reflection channel, then attach a sphere map node to it's background color channel, and then attach a image map to the sphere map's color channel. Usually the reflection image is related to the background elemets or image. 
 (Lightening the reflect node's background color will increase the amount of image that is reflected in the car paint; I tend to use a dark grey for this.) 
The downside to this method is that there are more textures for your computer to handle, and the preview display becomes unreliable. Some scenes will also require much trial and error adjustment to get the color & intensity of the raytraced reflections to match the colors & lighting of the other items in the scene.

2.) A visit to the Peugeot website (http://www.peugeot.com/en/default.htm) has uncovered a couple of detail problems with the 206.  
  1.) the body moldings should match the paint color.
  2.) the front logo should be surrounded by black. (in the 206 model the moldings and logo black are the same material zone. Also consider the vents in the hood...)

These are small detail problems, and can be easily solved by either creating new material zones in Poser, or even better by assigning a material to the particular group in the 3D modeler before importing to Poser. (Materials assigned in a modeler will probably still need to be modified after importing to Poser; but each part will have it's own zone.)

- - - - - -

Next time I'll take a look at how to add or change a model's material zones, and / or make it's "normals" consistant in Poser. (Perhaps I'll also get around to the comparison of higher polygon/ higher detail freebie autos)
