Ok, thanks for answer. So it's not that easy. But I'm quite sure it must be possible somehow. By using nearestObjects I get an array of object's IDs and their models (p3d). Could I take an advantage of knowing all the p3d that are used for roads? For example could I convert the array element eg. [object 29549: asf10 25.p3d] to string and check if part of the string matches one of elements of a global array eg. [asf01 00.p3d, asf02 00.p3d, etc]? Would it make any sense?
