Playing the same GIF on multiple screens

You can replace the Screen property with Screens, which is a table of UI elements / textures, to show the same GIF on multiple screens.

local GIFPlayer = require(game.ServerScriptService.GIFPlayer)

local screens = {
    workspace.NormalScreen1.SurfaceGui,
    workspace.MeshScreen1.Texture
}

local gif = GIFPlayer.new({
	Screens = screens,
	Image = "rbxassetid://3528512681",
	FPS = 24,
	FramesPerRow = 6,
	Frames = 26
})
