ok, you're right in what you say.
if my English is bad and we can not properly understand I apologize, but I will try to make it clear.
the problem is the next:
the player can walk around the level without any problem.But when the player is on the elevator and Elvador is go up . The camera begins to flash. however when elevator is go down and the player stay on the elevator the camera does not do this.

I think it may be by the c trace . The move c. maybe the way of moving the Elvador. i dont know... any helps?
thanks
