Making glass in 3dmax

[gamecubicle]

Heya, im moddeling a Watch in 3d studio max, but i run into a problem. I know how to make glass, at least very ugly looking glass... You can use a Glass lume map and a Flat mirror map to make it look a little bit like glass.

But in this project i really want glass that you dont see, the only reflects light, and only works as a mirror from one side (if it works from 2 sides, you see the watch itself in the glass. And that is not what i want)

Anyone knows how i can do this? Or does anyone know a good tutorial that explains this? (maybe some vray or mental ray options?)

Hope someone can help me.

Thanks/

I´m not sure I understand what you want, but for the part where you say that you want it to reflect from only one side you could either model your glass with only one side, or use two different materials on a glass modeled with actual volume. If you wan the glass to just reflect stuff simply make it 100% transparent and set the specular and glossiness levels to zero.

I found this here in a thread it might help you out or at least point you in the right direction, to get started.
Unfortunatly i can't remember who originally posted it as i saved it to my HDD for reference, so a big thanks to whoever it was anyway.

Press 'm' to open up the materials editor, select a sphere (any grey one of your choice). In the diffuse colour box change it to black.

In the maps rollout of the materials editor next to refraction click the box that says (none) and choose raytrace from the list. Leave the settings at 100.

still in the maps rollout select the box next to reflection, this time choose mask from the list. In the map box select a bitmap that you would like your glass to reflect. I used a picture of a restaurant dining room, since it seemed quite appropriate. Click the goto parent button (like a bent arrow, just below the spheres in the mats editor). Click the mask box and choose falloff, leave the default settings and click the apply to object button to apply it to your glass.
