Lighting Options:
-rescale_lights xxx rescale light intensity values by
specified factor (performed before other lighting overrides take effect)
-auto_skylight xxx
force use of ambient occlusion lighting, auto-rescaling direct light sources to
compensate for ambient occlusion factor (use value 0.7 as a good starting point)
-add_skylight xxx
force use of ambient occlusion lighting, manually-rescaling direct light sources to
compensate for ambient occlusion factor

disable specular highlights
Transparency Shading Options:
-trans_max_surfaces xxx
limit the number of transparent surfaces shown to the number specified
-trans_orig
original implementation **
-trans_raster3d
Raster3D angle-based opacity modulation
-trans_vmd
opacity post-multiply used by VMD
Transparent Surface Shadowing Options:
-shadow_filter_on
transparent objects cast shadows **
-shadow_filter_off
transparent objects do not cast shadows
Fog Shading Options:
-fog_radial
radial fog implementation **
-fog_vmd
planar OpenGL-like fog used by VMD
Surface Normal/Winding Order Fixup Mode:
-normalfixup [off|flip|guess] (** off is default)
Antialiasing Options:
-aasamples xxx
maximum supersamples taken per pixel (** default is 0, or scene file determined)
