As the title states, how do you create SCars PROPERLY? I want to make a Panzerkampfwagen VIII "Maus" and Panzerkampfwagen III, Ausfuhrung N but lack the knowledgeability on how to do this properly. Any pointers and tips would be greatly appreciated as I would like to try this out on my own accord.

On a sidenote: I plan on crediting whomever helps me with this on the Steam Workshop page for the item, even if it does not get much attention - I am sure it would still be appreciated.
