So I accidentally put the post in the wrong category, so here is my post again with a few responses to some questions.
I came across this cool camera system that uses some method to show the camera view.

They also have a system called Blox Digital where you can watch things on a screen in Roblox.
I have been trying to figure out how they do this and all I have figured out so far is that they do not use viewport frames.
I have contacted the people asking them, and they confirmed that they don’t use viewport frames due to them being “too laggy”. They wouldn’t tell me how they did it which is fair because it seems like really advanced methods.
