I tried to remove the chunk from my droidfighter, so it just explodes and there wont be any chunk around.

When I removed the chunks and played the droidfighter it works all fine, but when I get shot down the droidfighter doesn't explodes but flies on and on and I can't control it anymore.

yes, that is the result of not having chunks, you cant do anything about it. you should use some invisible dummymesh as chunk.

Okay sounds good. What's dummymesh

a mesh thats doesnt really appear ingame (i dont think ist the official term, i just thought that it was fitting) like those used to attach effects e.g. the beachexplisions on kashyyyk etc.

Okay alright I will try those. Thanks already.
