On the documentation it mentions that there can be an unlimited number of cameras in a scene. However I am wondering if a high number of cameras in a scene highly affects performances or if it is barely noticeable, say in an extreme case of a hundred cameras for example (not running at the same time though)?
I guess it depends how you use them and how many you have them running at same time, of course if you have even 5 camera all rendering the game scene, you may run into issue ^^.
otherwise i think it pretty common to use more than 1 camera , just for put HUD or havong some kind of minimap stuff ( those just rendering only these part )
What I had in mind is to put several cameras in various arrays divided maybe between “close-up” “middle shot” and “far” and to randomly pick a camera from those according to animations file (so for exemple, for animation1, a camera would randomly be picked from the “close up” array) so that even if it is the same animation played, the camera view would be randomly different.
So there would only be one camera rendering the scene at a time.
