Why you won't use at least the physics software for what it is supposed to be instead of scenes like this? you have a story making very simple scenes, usually of a character gift some someone for algo whatever thlon,that someone can make that thing. Most good scenes need the play button to work the scene, this takes no effort, intellingence or creativity to make such scenes like this, start knowing about using the play button, and start making scenes that makes sense.
This doesn't makes sense and doesn't need the play button
