Creating the Mesh (v2.49b)
This tutorial takes you through creating a simple steam loco in Blender, starting with using background images to get the proportions right and detailing all of the steps needed to create the loco body and bogie.
It does move at a fair pace and you will need time to digest the instructions - building any sort of model for Trainz is not a five minute job and you will need a lot of patience.
Also to save you asking I can't supply the drawings used in this tutorial as they appeared in the Railway Modeller and are copyright. If you really must build another Y7 screenshots of my finished model can be downloaded here.There are, however, plenty of other models that could be built instead.
