Warbreakers - Modelling Update

Whilst I continue to work on the texturing ideas (after some help from Alan), I'm also still working on the rough models to try and save time later.

The Flugbombe has had the engine updated, and little details like the bomb-collar added.

The big change on the Panzerbombe was the replacement of the straight-4 engine with an air-cooled V4, which has the advantage of looking more interesting (when detailed) and also matching the air-cooled engine of the Flugbombe.

And, for an experiment, I added individual link tracks (the alternative is a sort of leather band track, which I'm considering on the basis that it would be much cheaper to produce, and therefore better suited to something designed to explode)
