How do I show reflections on windows?
To show reflections, select Material > Type > Openings. Under the Group, double click to place an "x"
under the Display beside Glazing and then double click the Texture column. From the Texture Folder, select Color,
and then choose one of the colors. While in this menu, place a check beside Reflectivity to enable. You can then
control the amount of reflection to be displayed by adjusting the slider bar. Close each of the opened menus at
this point. To enable reflections on this image, select Options > Render Options and place a checkmark beside
Reflections. Close the menu and select Regenerate.
