If you are cranking things out like that after a week...
Just to clarify, this model wasn't made in one week. It was first started around six years ago using 3D Studio VIZ and was originally released for MSTS. Last December it was almost completely rebuilt in 3DS MAX in anticipation of Train Simulator 2, with a lot more detail, improved textures and closer attention to prototypical dimensions.
This past week, I reorganized and re-exported the textures, renamed the various parts of the model and created the relevant XML blueprints. After the first successful export, I examined the model and made a first-pass list of items that I thought needed fixing. Many of those items have to do with the unique way things are done in Rail Simulator.
What you see here is a first look at a work in progress with much to be done: shadow shapes, LODs, tender, animations, sounds, cab, crew characters--to name a few. Still have quite a ways to go before it's released!
