Hey y'all! I have a question (maybe that's why I am posting in the questions forum?

)
Okay, so there are four camera modes, and f1 does first person. However, it does not *actually* make you look from where your eyes are, it makes you see stuff from above your characters head... here are some screenshots of what I mean.
Here is my character, Boo, inside a size 2 by 2 by5 Hammy tunnel mesh. She can clearly fit inside, with a little room above her head. (shes a little big bigger the minimum size)

However, when I switch the camera from f3 mode (free movement) into f1 (first person) her actual viewpoint is inside of the mesh!
So, my actual question is... is there anyway to lower the actual viewpoint so that it matches where the eyes are, perhaps even a bit lower?
Also, one reason I may think it is like this is because the viewpoint does not change, no matter the size of your character. Therefor, for a default character, the viewpoint is actually at its eyes, however, shrinking your character down to what mine is makes the viewpoint quite aways above its head. Is that true?
In case you where wondering, I am attempting to make a underground burrow system, that only Fennec foxes can enter, which means the entrance needs to be small, keeping big butt people such as lions out, however if you cant actually *see* what you are doing when you are in the burrow, well, that just sucks xD so even if you cant help me with my question, having any advice on how to help fix this issue would be nice c:
Thanks for taking the time to read this! <3
