I have about half a dozen Halley's on a moon, throwing it at a planet, but the Halleys dont have any graphic effects or animations that shows the boosters are actually doing something.(But the moon still gets thrown at the planet.)

hmmmm. Can you set "Virtual Texturing" to Medium in the in game settings. Also try with Anti-Aliasing turned off.. maybe one of these options is interferring with the graphical effect of the halleys. When i use Uber setting in virtual texturing i get missing effects and explosions. If setting these options works and you see the missing effects let me know and i will alert the dev's to the issue so they can fix it.
It's known issue: PA#2215 Most likely for you halley flame effects appear, but somewhere in deep space.
I didnt notice any, but Id have to check. Last time I was about to try with Medium Textures, I got that crazy graphics glitching.
The Halleys have had that glitch for awhile the flames are dispaced out into space even when I run on linux. It would be nice to have the effect fixed so the moons have some pinaz. Is it a vertex cordinate mapping problem?
