I would recommend that you use a 3d program.
Not going to tell you how to use one of them.
Before you start working on a new model, maybe you should see how big a difference it will make. It could be you could get a very similar result with one of the exicting models. Remember the scale of the game.
Have started writing down some
tutorials on Automata Modding.
Take a look there and you can return with any question to this thread. (Please!)
1) Would I have to use a special program to model and create the vehicles (like 3DS Max or Milkshape), or could I just use the BAT GMAX tool?
BAT/Gmax can't be used. Sorry. I use MilkShape3d, myself.
The good thing about MS3D is that it does read the 3d files that is exported from the reader.
LithUnwrap on the other hand can read these files.
2) When I program the replacement props of the vehicles and the additional vehicles that appear, what would be the IIDs and GIDs needed so that they could work with the in game prop families?
Not sure about that. I would only change the IIDs and not the TIDs or GIDs. You will need to dig out the TGIs from the simcity dat files.
Hi, I want to add some new vehicles pulling trailers, and there are just a few things I'm not sure of yet.
1. I want to add some trailers to specific classes (group ID's) of vehicles, how would I go about this? I assume that I will need to define them as a new group with a vehicle script, but can this be done just by defining a new trailer class so that they will attach randomly to pre-existing group ID's?
2. How does cargo attach to the flatbeds? I havn't yet discovered this in my diggings into the simcity1.dat file...
Any info related to trailers and semi's (and car trailers) will be helpfull to me, as I'm still looking at the files figuring out what's what.
Not sure about these questions, but maybe or maybe not you can find something in
Swampers files.
