I fooled around with the files in my Freelancer folder a bit.
-you can shut off Trent's audio by copying "nnvoice.utf" to "trent_voice.utf" in hte "audio" folder.
-in the "charaters/body" folder you can turn trent into a nomad squid by copying the "worm" file to "pl_trent_body". If you leave his audio on its highly amusing to see the squid talking and the guys saying "Nice to see you Trent".
-You can give Trent any other uniform by copying the files in the folder to pl_trent_body.
-if you try that with a female body it gives you a horribly deformed muttan with trents head.
-cant seem to get rid of Trent's head. Probably its impossible because he has different facial animations than other chars.
So that way I made Trent a squid and shut off hte audio to see how a removed trent would feel. The biggest drawback is that every character calls you Trent after the first time you met him, as the first thing he says when the dialogue starts.
The non SP storyline dialogue audio files dont seem to be easily accesible like the storyline ones. If anyone knows how to, can he tell me?
So if Trent was to be removed, you would also have to remove the first line every npc char says to stop them form calling you trent. Maybe it can be done without too much work by mayking a script to do that. It would also shorten the conversations, making them less annoying and making you watn to press esc less.
Still its less easy than I thought.
Giving yuo another chosable avatar than Trent would not be worth the effort imo, cause nobody else sees you anyway.
