| Initial value: | 10 |
The render engine analyzes the results of a rendered image between iterations, or levels, to determine where improvements can be made. Increasing the render time improves the quality of a rendered image as more iterations can be performed, but the improvements made between iterations might become less distinguishable with long rendering times.
The RENDERTARGET system variable indicates whether rendering is based on a fixed number of levels or a time limit to control the quality of a rendered image. The rendering time limit is specified by this system variable, while the number of levels, or iterations, is specified by the RENDERLEVEL system variable.
