Reflective Shader - Quality Tab
The Quality tab contains settings relating to the quality of reflections. There is currently only one setting.
Number of samples: This sets the number of samples used to calculate soft reflections when Ray traced reflections is enabled and Reflection softness is greater than 0. More samples produce a more convincing soft reflection effect, but increase render times. If Reflection softness is 0, the reflection is rendered with only one sample, regardless of Number of samples.

A sample refers to a value or set of values at a point in time and/or space. The defining point of a sample is that it is a chosen value out of a continuous signal. In Terragen 2 it is usually a mathematical (procedural) function that is being sampled.
