Internal Density Effects

Color

With these controls, you can specify a transmission color based on thickness. The density color gives the appearance of color within the object itself, like tinted glass.

• EnableTurns color density on or off.
• Color swatchDisplays a Color Selector. Choose the transmission color.
• AmountControls the amount of density color. Reducing this value reduces the density color effect. Range=0 to 1.0. Default=1.0.
• Color MapAssigns a map to the density color component. Use the check box to enable or disable the map.
• Start and EndA thin piece of tinted glass is mainly clear, while a thick piece of the same glass has more color. Start and End Distance, expressed in world units, controls help you simulate this effect. Start is the position in the object where the density color begins to appear (Default=0.0). End is the position in the object where the density color reaches its full Amount value. To have a lighter effect, increase the End value. To have a heavier effect, reduce the End value.

Fog

Density fog is also a thickness-based effect. It fills the object with a fog that is both opaque and self illuminated. The effect is like smoke trapped in a glass, or wax at the tip of a candle. Colored fog in tubular objects can resemble neon tubes.

• EnableTurns fog on or off.
• Color swatchDisplays a Color Selector for choosing the fog color.
• AmountControls the amount of density fog. Reducing this value reduces the density fog effect and makes the fog translucent. Range=0 to 999999.0. Default=1.0.
• Color MapAssigns a map to the fog component. Use the check box to enable or disable the map.
• Start and EndStart and End Distance controls, expressed in world units, adjust the fog effect based on the object's dimensions. Start is the position in the object where the density fog begins to appear (default=0.0). End is the position in the object where the density fog reaches its full Amount value. To have a lighter effect, increase the End value. To have a heavier effect, reduce the End value.

Render objects inside raytraced objects

Turns the rendering of objects inside raytraced objects on or off. Default=on.

Render atmospherics inside raytraced objects

Turns the rendering of atmospheric effects inside raytraced objects on or off. Atmospheric effects include fire, fog, volume light, and so on. Default=on.

Treat Refractions as Glass (Fresnel effect)

When on, applies a Fresnel effect to the refraction. This can add a bit of reflection to the refracting object, depending on the viewing angle of the object. When off, the object is refractive only. Default=on.
