To do engine glow in Blender is pretty simple and takes just 2 steps.
Select the object that is to glow, usually a flatend rectangle, and select the color you want it to glow in material, usually red or blue for space ships it seems. Try these settings:
I think the important thing here is to just crank the Add and the Emit right up.
So now you have a very bright blue rectangle, and will need to add some glow around it, for that
add a new plane and delete all but one of the verticies.
Add a new material and make it a similar colour, but much lighter and select the Halo button. Try:
R: 0.226
G: 0.750
B: 1.000
Now depending on the size of your rectagle, the single vertex Halo size will have to be adjusted,
as well as the Alpha and the Hard. Try:
Halo Size: 3.000
Alpha: 0.770
Hard: 47
Add: 1.000
Place the single vertex on the surface of the glowing rectangle right in the center. Now also add a
lamp right where the vertex is and give it a short glowing distance, say of about 3 or so and crank
the energy up to about 2, or so. :o)
Make sure to check out what you’ve done by rendering both front on and side shots to check out how it
looks. This is basically how i get engine glow for my ships like:
