3D Problems
>> [1] a graphic feature (e.g. taillight) would have an attribute set
Have you tried rendering this object (taillight) with a self-illuminated
material in a hue that won't show up elsewhere in the rendering? For instance,
set up one color of your 256 color palette to be a bright magenta. Exactly
match the RGB values in a material, and make it 100% self-illuminating.
>> [2] It is important to be able to able to generate artwork with a specified
>> number of colors (e.g. 256 or 16 or even 14.)
Many people use AniPro to build custom palettes. At render time you can force
3DS to use your custom palette.
>> 3) Support for multiple palettes.
If you are refering to rendering to a specific set of colors, the same logic as
above applies. If you are refering to the colors included in a flic file, I
believe that AniPro will allow a unique palette for each frame. This isn't
recommended though, because the screen will "flash" each time the palette
changes.
