I have some problem of controlling dielectric material reflectivity.

Greetings

I have some problem of using dielectric to make the glass, the reflection of the glass is too strong. I created a blinn material and dielectric material, then in the blinn shader group attribute, I select custom shader, I link the dielectric material to the material shader. (the screen shot of the setting is enclosed)
The dielectric shader setting is: lor in: 1.65, lor out: 1.65, Phong_Coef: 10

While there is no option to control the reflection in the dielectric material attribute, so I tried to decrease the reflectivity in the blinn attritude. However,it doesn't work. I wonder how to control the reflective.

In the scene, I use a sphere with a high incandescence value shader with final gather to illuminate the scene, and I use 1 spot light outside the window as a key light, and I create another directional light at the opposite direction to the key light as a fill light.

actually how to control the reflectivity, if I use dielectric?
I want to enclose my working file, but the file is more than 500 kb, it cannot be uploded.

Thanks so much![/img]

Sorry about I ask so much.
Is there any good online tutorials that teach interior lighting (mental Ray), and making glass shader, and high reflectivity shiny metal shader?

Thanks so much.
and I need to figure it out how to upload my working files ...
Because I don't know how to explain the situation that I need to fix.

once again, thanks
