how do i get to make the glass reflect
Under the Corona
Material (Surface) Settings, in the Reflection setting, make sure the Color is white, the Level is anywhere between 0.5 to 1.0, the Glossiness is 1.00 and the Fresnel IOR (<-most important) is between 1.5-3.0 (you decide how reflective you want it to be by adjusting that).
And then you can adjust the Refraction values to adjust how much you can see through the glass, so values of Level - 0.75, Color - White (or light greenish-white) and Glossiness of 1.0 and IOR value of 1.52 (the real world Refractive index of glass) should give you realistic looking glass.
If you want to change the color of the glass, you can change the Diffuse Color value but more effectively it's better to change the Refraction 'Color' to a slight tint of the color you want, or the Reflection 'Color' the same way to see more of a reflective tint on the outside.
But the most important values are the Fresnel IOR (higher values mean more reflection so maximum value gives you a mirror), Reflection Glossiness (better to leave it just at 1.0 unless you want a glossy blurry reflection in which case use lower values than 1).
In the same way if you adjust the Refraction IOR (higher value gives you more refraction and bending of light) and the Glossiness to lower value, you begin to get a frosted glass look (best value is something around 0.5-0.75 for realistic looking frosted glass with higher IOR of around 1.8-2.0. Try to avoid putting the Refraction IOR higher than 2.0 or 2.5 because that's the Refractive index of diamond and you'll get strange results)
So to summarize:-
From you menu:
Options -> Attributes -> Surface (Settings) -> Select your Glass material -> change the Engine settings to 'Corona
Renderer' -> make the changes in the 'Reflection' and 'Refraction' sections.
You should see the changes in the material sample slot right away as you change, and if you want you can turn on the interactive renderer while you're changing the values (or before) to see the changes in the render model AS you're changing the material value.
Anyway, I hope this helps.
