@femboy as far as I used that mod with all the scripting it has - I did not find an actual free cam I was talking about,
Jip's cinematic mod dedicated to creating a camera movements pre-set on the motions (like a keyframe animations). But not dedicated to solving main issue Im having - Clipping to all sorts of terrain to look from bottom to up.
As far Cinematic Mod is good - but thats not what Im looking for.
