Maximum Ray Depth and Transmissions

Transmissions are controlled by the Maximum Ray Depth setting which determines how far light travels through transparent objects. The levels rendered include each side of the object. So, if you use a cube, remember that it has two sides for transmissions to go through. If you use a 2D Face, only one side is used for transmissions.

Just remember when using this feature that the more levels of transmission you select, the more render times are increased.

The examples below use five thin cubes placed one behind the other (remember, two sides per cube).

For brevity's sake, "MRD" will be used instead of "Maximum Ray Depth."

• With the MRD set to 5, Bryce renders five levels of transmission. Since the cubes have two sides, light only goes through the first two cubes and half of the third cube. The levels behind that render black. The edges of the cubes show the same levels of transmission depending on their placement.
  
  
• With the MRD set to 8, you can see clearly through four complete cubes.
  
  
• With the MRD set to 10, you can see clearly through all five cubes.
