Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
At this video you can watch the new Nebulae made by Nawrocki and me.
If you want make your customized nebulae, you can take the images from here. Hubblesite.org There are many options.
Whats that white thins coming from the eclipse? Looks weird, And you have to change the velocity of turning left or right to the eclipse, if its a big ship.... Have to be slow, just my thoughs great job you have there!
The white thing is not white really, it is more as a normal tractor beam and it is alternative tractor beam, it slows enemy starships.
About the movement.This EAW and really you can not avoid the fast turns from a starship added like this. You can try it, even if you reduce the turn speed, you will see it again making this. I have been modding this game many years and I have tested most of all. I have added some new code but there are not anything for avoid this.
