Simple Real - Time Crowd Simulation in Unreal Engine

Recently I am participating in a project which need to create a large number of crowds in real time for Virtual Production. First, I found a plug-in calld Atoms which provide several kinds of crowd simulation. However Atoms cost money and......I don't want to pay for the it lol. So I decide to do a simple crowd simulation from scratch. For the mesh part, I finally found the vertex animation(VAT) method. Because it is only a texture, it can save a lot of computer performance. I refer to this video for creating VAT. Interlakes explained it in great detail. https://www.youtube.com/watch?v=aYYifbcUflg&ab_channel=Interlakes For the scatter part, I currently tried 2 methods. One is to add niagara to the spline. (I think add instance static mesh to spline should also be able to achieve the same effect) Another method is blueprint's box scatter. The blueprint is created by Anh Nguyễn. I just do some adjustments. It can automatically detect the surface of the object. It's free, if you want this tool, you can download it here: https://www.youtube.com/watch?v=pp1FN3K7JdA&ab_channel=AnhNguy%E1%BB%85n For other information, I refer to the official Unreal Engine tutorial. However, this video seems to omit many steps. It is difficult to follow the tutorial and create the same results. But the video shows the possibilities of crowd simulations. It's worth studying in depth to see if you can make those cool effects. https://www.youtube.com/watch?v=CqXKSyAPWZY&ab_channel=UnrealEngine ArtStation: https://www.artstation.com/storm_s 3D models: Cyber Samurai--KhoaMinh--https://sketchfab.com/3d-models/cyber-samurai-26ccafaddb2745ceb56ae5cfc65bfed5 Ice Hockey Stadium--studio lab--https://sketchfab.com/3d-models/ice-hockey-stadium-7cb1e48f4720402c899cb6c319fff577 Music: Blurry Vision - Corbyn Kites--YouTube audio library My PC: AMD R7 2700X RTX 2070 Super 32G RAM
