Why can is it that when I switch to an other players view while watching a demo, suddenly he disapears?
When you record a client side demo, to keep the amount of data down, Unreal will track only the action within a certain range around the client (line of sight plus a bit more). So if you switch to an other player, simular to spectator mode, you can see his action only if he is within that range around the recording client. When the player leaves the range, he will disappear. If you want to be able to switch to any player, you have to use a server side demo (see below).
