I saw it again. It does not appear to change with distance.
Well, it's the first time you say it doesn't *change* with the distance. However, as I've said, it's not really dependent on the distance, but how the object is big on screen, regardless if you are close or far which means, you might be far, but zoomed in, or close and zoomed out, what counts is how many pixel the object will take on screen.
I've checked it, and can't find anything wrong with the firetruck at Hilo. It was the static or the animated one ? I see both of them correctly, though.
Have you set the SmallPartsRejectRadius tweak to an high value, like more than 2 ?
