I don’t exactly understand. Wouldn’t setting the camera every frame be worse than setting it one time? Not to mention the potential lag it would make.
Anyways:
In the video, the camera type doesn’t seem to be changed at all. I, as said in my reply, was going off of the title alone in that section of my reply. I believe the game to be using this as it is the most popular one I could find: EZ Camera Shake ported to Roblox
