TIP If your scene has transparent objects such as glass, increase Bounces to be
greater than zero. Be aware that this increases rendering time.
Increasing the number of bounces increases the level of global illumination and the
amount of color bleeding in the rendering.
Cone Angle Controls the angle used for regathering. Reducing this value
can result in slightly higher contrast, especially in regions where lots of small
geometry casts shadows on a larger structure. Range=33.0 to 90.0. Default=88.0.
All rays initially cast are limited by the cone angle
Volumes [toggle] When on, the Light Tracer regathers light from volumetric
lighting effects such as Volume Light on page 6520 and Volume Fog on page
6512 . Default=on.
