Good evening (as it is for me right now),
Here is the project file of the intro animation. It's all in one file as I don't like to edit clips for short sequences like that. You'll find that the crowd looks quite empty - that's because the crowd density factor has been turned down. Also for playback performance the plant remeshing has been turned off - find the volume nodes at the right end of the nodetree and turn them on to see the effect. All the other things are in place and should work. PS: I didn't organize the nodes too much as this is what you can use the specific plant projet file for. Experience the mess I'm working in 😁
