hi Pete
I will not lie it has a massive poly count but it seems to make no difference in TS12 very smooth, maybe because it is broken down into small asset sections and its not one big massive hit, Trainz 2010 runs good with it installed, all up Pete there is about 8 asset section,last night i was playing around with it to see which is the best way for people to put this together and the easyest way is the decking first and the lower arch, it is much easier to do it that way rather than have all the other section of the bridge there at the same time and all wanting to move around,
the decking and the lower arch are the main assets to get into position as there is not much room for error with these 2, so get those 2 right and the rest is pretty easy,
Trainz 2009 really cant say . but i will test it and see how it goes.
