I myself, as well as many other Youtubers, have wanted a Free-Roam Camera mod for the longest time.
On two separate occassions this was accomplished, but in both circumstances, the modders withheld a public release. The two mods I am referring too are shown below to give you an idea of what I am talking about.
(For the second clip, skip to 7:10).
It would be preferred that the mod created matches the first clip. If you have more questions you can email me through firstname.lastname@example.org or through the modding Discord (The Bread Pirate #4334). I will make sure to respond to all comments for this request as soon as I can.
(P.S. I don't know if people care all that much about the bounty system, but I racked up quite a few points with the Oblivious Enemies mod so the bounty starts at 300 points)
