For our latest release of Movie Maker 3D we worked on making it even easier for users to create realistic 3D movie scenes. You can now position models anywhere in a scene, including on animated animals and avatars. Implementing this required me to really dust off my matrix math skills but I think the effort was worth it. I hope you'll give it a try! https://apps.apple.com/app/movie-maker-3d/id538150047
