For several weeks I've been working on that, just with the process of exporting and scripting. And this also includes all the animation process, all done in 3Ds.
This model is owned by Trainz Forge (thanks to Daniel Gollery), kindly allowed the model to work on Railworks (TS2018). It has been very rewarding, although there are flaws in the animations (something I have not completely mastered at the moment), it's pretty good and at least it works.
To finish the first version, I need to include sounds, particles and a view of the interior of the cabin. It has all the wheels excited and even the bell, but the internal gears are not animated, maybe I'll find out soon enough. I'm having a very special help from a programmer friend so this work is completed, although it may still take a while, this is my first, the idea is that I can make other steam engines for Railworks, including Trainz Forge models.
Below are some pictures of the model on my TS2018:




It looks beautiful, does not it?
I hope it works out!
