NPC Manager - Crowd Optimizations with over 500 NPCs! 

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 :)

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 :)

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

@@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 :)

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

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).

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 :)

Soon :D

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 :)

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.

I havent tested once its nativized, but I would assume it would be even better :)

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?

@@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

Thank you!

Hi there, you can get the asset here - www.unrealengine.com/marketplace/en-US/product/npc-manager-system

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

Please take a look at the tutorials to learn how to use it :)
