I just downloaded gmax for the first time and I want to build a Norfolk and Western water tender like behind the 765. I might use the trucks from the J 611 tender. Since I'm new to gmax, I had Trainz for over 10 years, at least 4 different versions, now I'm mostly using 2010 and I also have 12, I'd like some help with this. All of the water tender projects I saw seem to be vaporware, and some creators like Paulz Trainz and wgkandsk (Bill) can build stuff for you for a fee, I was thinking on asking Bill to help me build one, in fact he has a site with Steve Lerro and they have one in the works but it was put on hold. It should be a simple project because all it is is a rectangular box with a curved top plus the detail like steps, hand rails, foot platform on roof, etc. I believe it is a little shorter than 765's tender, and a little lower. How do you attach the trucks to the main body model? Can you do it in gmax or do you have to use some other program? Can you import directly to trainz format in gmax? Also how do you attach couplers at both ends? It's a shame there's such a shortage of excursion era equipment for Trainz like water tenders. 630 has a nice water tender, too it's the same shape with a curved roof but smaller than the N&W one. Both tenders exist in MSTS but not in Trainz. Right now, I'm concentrating on the N&W one. I'm going to play around with gmax and see what happens. I have to register it yet.
