VketVideoPlayer
This is a video player Prefab.
You can set it up to play a video when a play button is pressed, when a visitor enters the exhibition space, or when a visitor enters a designated area within the exhibition space.
Starting with Vket 2026 Winter, only one video player (VketVideoCore) is placed in the world and shared between exhibits. The VketVideoController placed in each exhibit sends playback requests to it.
Video playback is not synced with other visitors (local playback). Playback stops when the visitor leaves the space.
Placement limit: Only one VketVideoPlayer can be used per space.
Videos must come from a URL. You cannot submit a custom video file for use.
This page assumes you have already opened the submission scene.
For how to create a submission scene, see the Vket 2026 Winter Submission Guide.
