Read the Realism Section of the TMO_Manual.pdf. It explains the changes and the rationale behind those changes of the External Camera View operation. It's part of the TMO experience to reduce the outlandish situational awareness allowed by the external camera depending on difficulty settings when playing with the TMO Mod.

2.) How do i get the next / previous camera back?

Ah, I see in your OP you've already done seen this so I must presume you are playing at a higher TMO difficulty level that disallows the External View altogether. if you want External View capability at the higher difficulty settings you will have to alter the contents of GamePlaySettings.cfg... (AFTER you have started a TMO v2.5 Pacific War Campaign, but BEFORE setting out on the first Patrol). To get the view back you must set NoExternalView=False. TMO at higher levels sets this to True. There are several copies of GamePlaySettings.cfg in the My Documents/SH4/... subfolders, but the one that matters is the one in My Documents/SH4/data/cfg/GamePlaySettings.cfg NOT the ones in the various saves during a patrol. Best time to alter this is when you are in port prior to starting a mission. At that time exit the game prior to starting a patrol and change the above mentioned File at that location and identical files in the in-port autosave folders.

Be sure to make backup copies of any files you are considering altering in case you have a glitch, then you can copy the original file back.

Hope this helps.
