For this reason, we recommend never having more than one video stream displayed at a time per scene. Videos are also not played if the player is standing on a different scene.

+Keep in mind that streaming video demands a significant effort from the player's machine. It's recommended to avoid playing more than one video at a time.

+If too many videos are playing at the same time in your scene, some will be paused by the engine. The priority is determined based on proximity to the player, direction of the camera and size of the screen. The maximum amount of simultaneous videos depends on the player's quality settings.

+- Medium: 5
