Some engines (Unity, Unreal) support animated textures that are formatted in a grid. However not all engines support converting movies into this format. After looking around for something that would do this and failing to find anything, I wrote a 3dsmax script to help out with this process. It takes in one or more avi’s and builds a subdivided plane with the corresponding frames mapped to the quads. It then creates a camera. All you need to do at that point is set the render size and render out the camera view.
