Ah...

Although I still don't understand the finer points, it think it will be sufficient for what I'm doing.

MeepII, in the reflections challenge I made a post with some more details on using reflections:

Quote
pecular value: Influences the amount of reflection. If you do this less than 1, the other values of a material have an effect, with 1 the material is fully reflective and the ambient and diffuse settings wont matter.
2 types of reflective classes: reflection or glossy
Rough value: The material exists out of the reflections, and a specular highlight on the material where a light is positioned. Changing the rough value will change the specular highlight. Smaller values will make it glossier, higher values will make it sharper. If you set it to 0 the material will be more accurate, since highlights dont exists in real life, they are reflections of objects.
For glossy reflections, this effects the glossyness of the whole reflection.

Specular maps don't influence the amount of reflection (yet).

In scene mode you can add a scene attribute called 'RayDepth' , setting an integer value for that will say how often light bounces from reflective surface to the next. Lower values will increase render time , but produce less accurate results.

It's not everything but it should be enough to get you on the way to experimenting!

Are your using a .97 version of a file? If you started the project in .95, it seems that some of the effects don't happen (at least for me). If that's the case I'd try to make a new project in the newer version. Otherwise, check your spelling, once I was trying to have a glossy attribute. I had named the attribute specular (make sure you didn't capitalize anything by the way, I done that too), set it to be a string, and typed glossy`. I don't know how I accidentally pressed the "`" key, but I did. The picture below shows reflection as a string inside the specular attribute (I set them up as separate attributes at first). So I hope this helps.
