Choose the shape of the bevel from this popup menu. The width, in pixels, of the beveled edge. If this is more than half the width of the widest part of the selection, no area will be left unbeveled. Positive values cause the selection to rise out of its background, and negative values make it sink in. The slider specifies the amount of texturing, if any.
Positive values make the texture rise out of the bevel, negative ones make it sink in.
Controls the shininess. Controls the size of the glossy highlight. Controls how much the selection reflects the Environment graphic. If you don't want any reflection at all, turn this slider down to zero. Gives the selection a glassy rather than opaque appearance.
