I'm messing around with Array 2S for a while and I noticed that you can't set up material IDs for your segments.
Whenever you create a segment, convert it to Poly and then apply an ID for it (for example - 1), Railclone mixs up everything and might display the segment as Material ID 5,4,3 and 6.
Help!
