So far I've gotten bits of software that handle each phase, so it won't be much more effort to combine it all.
As a test, I've generated this.
I once helped build a 7.3L Ford Power Stroke, then we painted it.
We called the color "pepto-bismal pink", and the flames were stenciled using a cut up piece of cardboard. I think we should have replaced the exhaust manifolds with ceramic ones, but oh well. Money, money, money...
Front shot. Flames on the pulley were ... different.
You can really get an idea of how shitty those exhaust manifolds are from this angle.
