so i have a problem of video playing on play mode but not playing when built, in the first scene i have a video playing just fine. Though the video in the first scene was attached directly to a video player, in the second scene where video is not playing, the video is assigned through a script as theres a lot of possible videos to be played depending on the buttons selected.
note that on play mode, there is no problem with the second scene unless i build it.
so i tried assigning the video from the first scene through script too, and the same thing happened.
As a guess, are the video files not in the Resources folder? If an asset is not linked to a scene/prefab that used it won't be included in the build. However all assets in the Resources folder will be included.
