Sorry to resume an old topic... 
I've just played a mission on Cyberolas' Burma map, attacking trucks running on a road. Soon or later those not destroyed by our fire arrived to some tree crossing the road and then started tu "bump" repeatedly against it.
Please, there's someone confident with map building that would fix also this map?
At present the only way I would know how to fix objects on roads would be to go along the roads in a map-maker version and to manually remove the offending objects one by one.
This is for maps with few roads not an arduous task. But on many maps of European areas, nigh on impossible without going stark raving mad.
Surely though some kind of (java?) tool could be devised for this? Auto-popping of map textures works in this manner I believe, objects are placed on textures with a designated RGB value. So the opposite should be doable as well: namely removing objects on textures with a certain RGB value.
For roads, there would probably have to be a range of RGB values set instead of just one, but that should be of little consequence to the basic idea i would think.
Too bad i have no idea at all, no notion or experience with programming anything at all.
