Here is the result of assembling my sci-fi assets into a scene, as astronauts
investigate an ancient alien artifact at sunrise on a distant world. The
material I used for the orange/glassy portion of the artifact was incredibly
slow to render, so it took almost two days.

As a post-processing step I also wrote a simple brightness mask scene file that
reads in an existing image and masks off (as black) areas that are below a
specified brightness threshold. A simple 5x5 Gaussian convolution matrix is then
iterated across the resulting masked image to blur the remaining pixels for a
simple glow effect (not sure if this is similar to what Sam Benge does for his

multi-pass rendering methods that I posted here a decade ago, the glow results
are then composited with the original image (e.g., the halo around the
