We have an animation which features two vehicles coming towards each other on a
road at night. The only lights in the scene are the vehicle headlights. The
problem is the road shoulder and the surrounding green grass areas are
flickering/changing colors as the vehicles move. Is this due to the moving
spotlights? We're rendering at 320 x 200. Currently we have just the 8-bit
display… is that our problem or is it something more sinister? Any input on
how to prevent this flickering would be appreciated.
I've tried messing with the ambient light, specular highlights of the
materials, brightness of headlights, etc. None of these things has eliminated
the problem; they've only changed the intensity of it.
You might try turning up the texture filter setting from the default of 0.6 to
a higher setting (1.0 or more). Either that or pick a custom pallette for
rendering or render with dithering off.
