not necessarily.
In skyboxes you may animate some parts of the nebula. Problem is that at the detail level we're talking about it would be very performance hit
Also, I have a little idea about localized nebs, which was expressed IIRC for the frist time by venom:
Make a nebula model, not too high in pcount, you don't need it, and map it so that it's invisible.
IIRC you can have invisible polys not colliding with objects, if not possible make this mesh with lots of weird intersections, to confuse the bsp tree generation.
Make many thruster models (the name in the hierachy) with shapes designed for this purposes, and map them with some animated nebula textures, and make the thruster glows in many directions/sizes.
Those thrusters will have to intersect the mesh, will intersect eachother and will be the various neb elements. The glows will be the hot areas of the neb.
Give to the pof hitpoints, and in fred make it undestructable but with a very low % of hull (not sure if this will work, but I think yes). As result you will see the lightning bolts that FS2 use when a ship is near to be destroyed over the invisible mesh.
