ok, this is around one year later from James' original post, and i am facing this exact same problem!!
i need to build a long road, but if it reaches more than 30,000 quants further than the origin, i get horrible distortions in the blocks (road, sidewalks..) !
what do i do?? aparently the problem has not been fixed by the new WED as Doug menitoned, because i'm using the WED version 5.3 , which comes with the gamestudio version 5.240..
please help!!
