Everything you see in the image was created using Bryce Nuski! Walls, table top, window frame, window gate, window glass, celestial chart, eye glasses, drawing compass and of course the sextant itself and everything on it and its base. SDL, yes, I did use a dome lighting setup. I tweaked the material for many hours. It's at a point where if I go just a smidge up on the reflectivity, the material starts to take on an un-natural glow to it like a false color. The material has no ambience set to it. Too low, the material gets too dark to make out the detail. I did try the photographer's reflected card trick to no avail. I finally placed a radial light in front of the sextant and turned off the shadows. I really don't think the TIR would have made much more of a difference on the render. Only would have given me more on the reflectivity and optics but no real image altering affect. Maybe one day I'll come back to it with finer adjustments. But right now, Im all sex-tanted out! :)
