Reflection

The reflection control dictates how much light will bounce off of the object to the other objects in the scene.  In effect, this determines how much like a mirror the material behaves.

Different values of reflection.
Bryce's default "mirror" material is a good example of this material attribute.   Notice the reflection index has been set to 100.
Bryce has a limit to how many times the ray will reflect.  If Bryce were to not have this limit, it could theoretically get caught in a loop that would prevent it from ever rendering an image.  For instance (see the image), if you were to erect two mirrored planes parallel to one another, put an object between them and place the camera so that it looks directly at the planes past the object, the resultant reflections could hang Bryce if it didn't stop eventually.

 

Refraction

Refraction indicates how much light bends when it passes through an object.

Different values of refraction.
To achieve the effects of Air, Water, or Glass, simply set the refraction as indicated.
  • Air:  100
  • Water:  133
  • Glass: 152

 

Mix and match the settings to achieve the effects that you want to achieve.

Remember that Material Lab functions such as: Bump, Transparency, Reflection, and Refraction significantly increase render times.
With what you have learned up to this point, see if you can pick all the attributes used in the Material Lab settings to the above/right that apply to the image to the above/left.

You are looking for:

  • Diffuse
  • Ambient
  • Specular
  • Specular Halo
  • Transparent
  • Bump--for this attribute, you are just trying to see it's there.

Site Note:

This is not meant to be an all inclusive instruction on every possible way to have made the final image or produce the desired results.  Bryce offers zillions of wonderful ways to replicate, multireplicate, reposition, etc.  in its powerful interface. Experiment!
