Reflective Shader - Quality Tab

Reflective Shader - Quality Tab

The Quality tab contains 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.
