exposure, can be automatic or logarithmic. Physical Scale indicates the
physical scale applied to lights.
• Materials : Apply materials allows us to render with the applied mater-
ials; if set to Off , it will render with GLOBAL materials that use the ob-
ject's color. Texture filtering controls the antialiasing applied to textures.
Force 2-sided applies materials on both sides of faces.
• Sampling : This area controls antialiasing effects, thus avoiding jagged
edges. We define the minimum and maximum number of samples that
will define each pixel, the sample mechanism, the number of pixels in
width and height of the interference area, and the influence of colors in
antialiasing.
• Shadows : The lamp icon turns the shadows' calculation on or off. Mode
defines a transparent shadow's calculation. Shadow map allows for soft-
edged shadows. Sampling Multiplier limits sampling for area lights.
