Hi
I'm trying to use particles (there was an older thread), basically
they're working, but they're attached to the aircraft, which makes them
not very useful.
Here are a few screenshots:

if i roll the aircraft, the particles will rotate along, and so on.
I mailed Luca Masera (he developed particles in the past) and he has a
different approach, He attaches the particle system to the scene root
and modified the particle system so the emmiter moves with the aircraft,
but not the referential.
A few screenshots of his work:

Unfortunately it seems his code is lost.
But it had a problem, when the aircraft switched tiles, the referential
was no longer valid. I'm thinking maybe this problem could be solved by
calculating an equivalent referential when the tile changes. This is
currently the big problem, and suggestions are welcome.
I also think it would be nice to have the particle systems available as
animations and that's my current approach but alternatives are welcome.
Cheers,
Tiago
