Good thing - video. Allows you to visually illustrate what a simple picture can not be explained ever. Add movement seemed forever frozen things.
But in a development environment Unity it completely unusable. You can start it and stop it. It's all available actions to the video. You want to change the playback speed, or rewind to another time? Forget! It's impossible.
Video - it's just a set of successive images. For simple and comfortable managing this set of images we offer you the components Texture sequence.
Texture sequence allows you, without writing code, upload images and display them in any public place.
Texture sequence component can dynamically create and manipulate it using the code.
