[Question] What would be the best tool to do this?

[DrakeFish]

Hi there. I'm not doing much model edit, I'm usually working with Memory Editing but I'm pretty sure this will be easier to do it with files edit. Basically I'd like to modify the "height" required in a map for the camera to stuck and for me to die. It's what happens when you get too deep in the ocean/fall under the ground/fall under some instances. I don't really care if the server does kill me, I'll probably do it in my 3.3.5a private server. With this I will record a video of an hidden zone I found that can't be accessed without this. I'd like to know what would be the best tool to achieve this.

Thanks.
