Sorry for the offtopic, but since it was discussed, I have a small question to ask you... I've come up with just now:
But when you unfortunately lose the prestige, and after u reset prestige, lose anyway "Challenges" (those who are in "Rank & Challenges") or not depends on the prestige?
Simply because I have almost completed all, I miss just a few that seem to be bugged*!
I know I'm interested about the little details ... I'm obsessive! I wanted to make a screenshot of this, but it would take a long time and then my game is in Italian!
In case you loose your rank you will not loose your challenges, setting or w.e. is saved in the mpdata.
As long as you keep using the same profile it's only your rank which is lost (and can be recovered by an admin (correct rank and prestige level))
Just checked the scripts of the final killcam and there already are dvars to define the length:
set scr_killcam_time 10 // length from killcam start to killcam end
set scr_killcam_posttime 2 // time after player death that killcam continues for
