Πριν μήνα

Displaying thousands of characters on-screen in real-time has always been a challenge - until now. Unreal Engine's Niagara visual effects system opens up doors to go far beyond what was previously thought possible and this presentation by Epic's Joseph Azzam showcases how you can utilize the power and versatility of Niagara to create massive crowds in real-time, and simulate a million units!
Plus, learn how to make the most out of Niagara's new features to create "smart mesh particles" that can replace basic AIs, allowing you to display an enormous amount of characters on-screen all at once.

Very interesting topic. The limitations on actor count per scene have always been one of my main problems with unreal. Especially gamethread related bottlenecks. I'm not really that familiar with niagara tho, so for me it's kinda hard to now understand what's possible with this strategy and what isn't (l mean with still good performance). Obviously the complexity of each individual unit here is rather low compared to strapping a whole AI tree on a character, but I suppose you could just do alot with additional code. But when you run that code you would probably lose a lot of the performance gain again. Still it looks like you were able to add a lot of functionality for what seems like almost no gamethread performance loss. So why exactly (on a technical level) is this niagara strategy better for large crowds, how does it scale so good? The instructions for each unit (like the position depending on the unit in front of it) should still be per unit (=> linear scaling) no? And there is still collision running, as we could see when u shot them. Why are actors performing so incredibly bad and this so incredibly good on the engine level? I fail to see where all the overhead on actors went, since they still scale so bad even if you deactivate a ton of their features like movement components, etc.

Are there ways to replace the particles with real AI when they are within the player's given radius?
Joseph Azzam
Joseph Azzam Πριν μήνα
Yes, just keep track of player position in blueprint and send it to Niagara, then the particles will check if they are in range and request an AI to spawned in their place.

I'm not sure what is causing your issue, but a workaround is to hit the record button at the bottom. Then delete the extra recorded frames inside unreal by right-clicking on the animation's timeline and removing frames before/after

​@Dindu Oh I see, didn't realize it was a different game mode :D.. Well I'm not sure if it's something to do with the game's source code or bad optimization, but historically you needed a lot of RAM to run this game with many units. About the other thing you asked, I just meant that those are the biggest battles in LOTR, where you would see the most player & enemy units at the same time... :D

​@JuGGerNauTT32 TWWH2 doesn't do 50k though, this is the laboratory mode which has some special optimizations to it. In campaign battles, performance is much much worse. I'm not sure why they can't bring those optimizations to the campagin though. What you mean by excluding Helm's Deep and Pelennor Fields :D

I don't know, I know Niagara is relatively newer, therefore they probably used another system. I would look for articles on the subject, as I sure they want to do a postmortem covering that. However, a guess is that they used a lot of concepts demonstrated in this presentation.
