Some bugs and function suggestions about the built-in camera in the game

Question 1: When using the green screen background function of the built-in camera in the game
Under normal circumstances, it should only remove the background
but keep the character model
However, in some worlds, after the green screen is turned on, the lighting of the character model turns into a green light all over the body like entering this green world. Green screen changes direct lighting. This is a disastrous problem in video production
Problem 2: The shadow of the character model is removed when using the green screen. I think the shadow should be kept or it will be very unreal.
And here is another suggestion. I want to add a camera level lock function to freely control up and down, left and right, but the picture is always level, which is very useful.
