I've been working on a rendered engine glow effect for the X-Wing. I'm not unhappy with the result. Image is straight out of Keyshot -- no shopping or post image processing. Backplate image is taken from the ISS. Ship mesh and textures were extracted (not by me) from the Star Wars Battlefront 2015 game, and updated with some of my own modifications.

Actually, I think the engine glow is quite effective. But somehow (?) a "hot spot" of orange at the foci of each engine would be the trick.

Looks sharp!
Looks great!
I'd add some depth of field with the camara or try post processing it with photoshop to give it a little of motion blur to make it look more dynamic.
How did you do the engine burn on keyshot?
