Ok, I'll try:
First I make a Plygon cube and I scale it abit.
Then I go to Hypershade, and choose the Blinn.
I double click the blinn, so I can get the settings for the blinn.
Then I go into Specular Shading and set the Reflectivity to 1.000.
And I also chance the Specular color to Black.
After that, I take my blinn and assign it to the Polygon cube.
Then I make a Polygon Sphere, scale it abit and place it just beside my Polygon cube.
After that, I go to my "Display Render Settings Window" (That's the global render, Right?) which are at my status bar.
Then I go to Raytracin Quality and enable the Raytracing, and I close the window. At the end I go to "Render the current frame" Which also is in my status bar.
When I've done that there is no reflection in the cube.
Hope you can help me.
Its rice, Its nice.
