I'm rendering a cab created within 3D Canvas, using POV-Ray, but I'm having some trouble with the lighting. As main light source in my scene I use an Area light (generates nice shadows). Problem is, when I move the area outside the cab, the shadows inside suddenly show 'bands' instead of a nice smooth shade (the same as in this topic: http://www.train-sim.com/dcforum/DCForumID10/186.html ). Moving the light back inside brings back the smooth shadows. Anyone an idea what the problem could be? Cas
The simplest solution would be to increase the number of point sources in the area light definition. From the 9 or 10 it appears you're using, to 45-50. Use the old setup for test renders, then kick up the horsepower for the final render. And make absolutely sure Jitter is enabled on the area light. Move the light a lot further from the cab model, as well. Also, make sure your desktop bitdepth is set to 32-bit. Modern graphics cards won't even miss a step at 32-bit... 16-bit is for people with Voodoo 3 cards . I mention this because POV-Ray defaults to 24-bit image quality; and if you're showing a 24-bit image on a 16-bit desktop, Windows is hacking and pruning the color quality.
