1. You need a dark gray diffuse color (for a perfect mirror it should be black, but often a dark grey color has a better effect on chrome).
2. Now go to add glossiness and specular level (there are no fixed values, the correct effect strongly depends on the light that you create. You can begin with the value 40 in both slots).
3. Go to maps and assign to the REFLECTION map "RAYTRACE". This will allow you to have REAL reflections of other objects in the scene on this material. The value in the reflection slot should be between 85 and 100 (a mirror must have 100)-( image 1).

Very often you need to have a environment which reflects on your object to achieve a good rendering. A good reflection will give a touch of realism to your object and will describe better organic shapes.
We will use a FAKE reflection. This kind of technique simulates the illusion of having an environment, whereby it is reflected on surfaces despite the reality that no such environment exists within your scene. In fact, all we will use is a simple image to create a Fake reflection.
After you have inserted RAYTRACE in the reflection map, you will see that the material editor is showing new settings. These are the settings of the raytrace panel (on the right side of the material editor you can see written RAYTRACE instead of standard). Like on image 2, assign to the NONE button in BACKGROUND a BITMAP (image 2).

After this step, you will see that the material editor is showing you the settings of the Bitmap panel (Image 3). Normally you must reduce the output amount of the fake reflection (this is the setting which will make more or less the image that you've choose as fake reflection to be visible). To make the image "less visible", you must go to "Output" where in the "output amount" slot you must put a value which is a little bit smaller than 1 (for example, 0.7). Normally the standard number 1 is too high a value.

Picture used as fake reflection for the rendering below.
With this method, you can obtain very good reflection results. Here below, you can see a sample.

On this image you can see the reflection of the gray environment + 2 white boxes + the fake reflection.
Aangezien je met 3D max werkt zul je wel behoorlijk goed engels kunnen lezen.
Deze tutorial komt dus zo via Google van het wwweb. Voor de afbeeldingen en vervolg-tips moet je even naar de bron van dit document gaan. Dat mocht op GV niet meer geplaatst worden door een beperking aan het aantal woorden.
