This page gives information on the Render Time Render Element.
Overview
The Render Time Render Element shows a floating-point number for each pixel's render time measured in milliseconds. The colors in the render element show the rendering speed as a range from black to white. The whiter the pixel, the longer the render time and vice verse. This render element works only with the Bucket image sampler. The Render Time Render Element is useful mainly for troubleshooting purposes.
