Yeah, I was surprised too. Simple line traces are very cheap in Unreal, and Im only tracing to the "Active" NPCs, which limits it to around 100 traces every 0.5 seconds. I'm working on further improvements so we'll see where we end up :)
Very nice, you've made something very similar to the Significance system they use in fortnite, although your is seems much more non-coder friendly. Any plans for releasing this?
Thanks Crown9! I do plan to release this, but no ETA yet, as I just started working on this. Still lots of ideas and features to add, so let me know if you have any suggestions on how to make this better :)
Aaaaand my wallet is gone again. By any chance have you thought if having them do certain things at certain "times" like a day and night routine, add fraction mechanics and make different movements for different NPC types?
Yup :) Already have the capability of loading different Profiles (lists of tasks) based on time of day. But the code is still really buggy so its not ready to show yet :P
Hard to give an accurate number, but if I turn off all the optimizations my FPS tanks at around 100 NPCs in the scene. This system helps me push over 500 keeping FPS fairly high. You can add many more than that btw, as long as you adjust the cull distance :)
Coqui Games, hello! You're doing great job with your system! But what if I have RootMotion animations, so it can't be just disabled... is there any chances to optimize?
Hmm, I havent tried root motion, but I think it should work. There are options to enable or disable root motion on the animation montages, so I would think it will work :)
@@GaMeNik19 Hmm, my setup uses In-place animations for movement so I can control speed, stopping, etc. I'm not sure I will support root motion for locomotion on the first release, but if its a requested feature I will take a look :)
@@vegitoblue2187 It depends. I'm actually not using traces to determine the distance (I keep an array of all NPCs in the scene and calculate their distance that way). However, I'm using traces to determine visibility. This means that even if an NPC is close, but cannot be seen, you can make it partially disabled. For this I need a trace on the Visibility channel to make sure it detects any objects on the way :)
@@CoquiGames hmm well there are many ways of doing it so I guess ill explore as many options as I can before I fecide on one. Also, does Unreal take advantage of multihreading for ai? That can potentially be huge in performance
If you use Metahumans, even without animation they are expensive. Add a paragraph, please. Texture replacement. That instead of Metahuman when the player does not see moves for example Mannequin.
Yeah for sure MHs are quite expensive! And thats a good suggestion - replace the skeletal mesh completely when they are far (more aggressive than LODs).
whats realy the probem, 41k polygons for the default Mannequin *500 = 20,500,000 Polygons That pretty much a hero Asset. lower polygons, low textures and possible more streamlined rigs. and the AI script do not need interaction over x distance. you can easy push 1000 +
Really good stuff. Surprised by the relative costs of the line trace. Glad to hear these optimizations will make it over to abk too.

from one coqui to another. AWESOME!
oooo this is amazing lol finally i can spawn more than 10 enemys in the map without my pc explo......xd amazing love it
looking good
Genius!
Wondering when we will have a chance to play around with this. :)
Soon :D

Hmm, Maybe you could put the script into components, so that if you wanted to add the system to a new character or controller it’d be really easy.
That's amazing
Thank you!

Comparing out of the box and your setup, what is the maximum npcs from the default ue4 and yours?

@@CoquiGames, I mean -- character motion comes from animation and if we disable it -- NPC will just stand

When will this be available for unreal Engine 5? I wanna make a game and this is perfect!!
Tysm for making this, I will buy this as soon i can :D
I plan to release the UE5 update soon after the official release of 5.0 early next year :).
I'm wondering how well it performance when you package it and make the blueprint native
I havent tested once its nativized, but I would assume it would be even better :)
How do I go about this if some will actions are animation driven for games like hitman and splinter cell
If you need the NPCs to still animate while being partially inactive, simply desect that option under Optimization in the NPC Controller component :)
@@CoquiGames isnt detecting ai using a sphere trigger eith a separate collision channel faster than trace?

Do these optimizations work in multiplayer?
It should be if he makes them server run instead of it running locally
I haven't tested yet, but I intend to make the system multiplayer, so it should work at the end :)
Kathode N yep rainbow 6 seems to do it this way for terrorist hunt
And how to use it?
Please take a look at the tutorials to learn how to use it :)
