Better fire effects for rockets

[FellowBob]

The rocket engine fire effects in ksp are all very unrealistic; except for the solid boosters and ion thruster, the rocket fire affects are all basically the same as each other but different sizes.

But if you look at real-life rockets, the exhaust shapes, sizes and even color change drastically with the engine type and air pressure. In most cases, at launch (usually at sea level) the rocket fire is huge, often as long as the rocket itself, and as it ascends into lower pressure the flame spreads out and gets shorter (and seemingly redder). In outer space, rocket fire is hardly even flamelike anymore; it spreads out very rapidly and is often almost invisible.

Maybe something could be added that makes the rocket fire spread and length inversely proportional to the local atmospheric pressure or altitude;

that alone would make a huge difference to the realism of the game.

Below are pictures of rocket exhaust at low altitude, vacuum, and in ksp for comparison

I'm not sure if Squad is pursuing realistic plumes much, but I would recommend RealPlume:

It's listed 1.4, but it works with 1.5 no problem.
