Detour Crowd AI Controller can not simulate a big crowd?

Hi, I am trying to simulate a big crowd of AI characters. It wont be something fancy but I want them to move to somewhere. The simulation is working fine until I got 50 characters. But when I add 51.th character to the scene the first character I placed is not moving anymore. More the characters I add after 50 the more characters are not moving in the scene. I checked world outliner and I saw that there are AIControllers for every character I add. For some reason Crowd AI Controller can not control more than 50 characters simultaneously. First I thought that it is because some limitations in the engine than I saw this guys video(Unreal Engine AI Crowd Example Video - YouTube) with 400 AIs and realise that the problem is about me. I checked forums for helps but could not find anything. What would be the problem in my case and how can I solve it? I need to control much bigger crowds for my project.

Thanks,

I too am having this issue. With AI Debug on it show the simulation status set to Not active… Hope someone can help us with this issue.

And then just like that… i find the answer i am looking for. There is a “Max Agent” number in the Engine - Crowed Manager" settings. I have attached a screen bellow to help you find it.

Here is a question I have with regards to the Max Agent setting:

Does that reflect the maximum amount of agents in that particular crowd? Or max as in the entire world? Also what is the maximum allowed before you take a performance hit?

Thanks!

Does it actually works with 300 AI with solid FPS ?

zoombapup from youtube helped me out. Go to Edit->Project Settings->Crowd
There is a variable for max AI characters preset to 50. You can increase that value as you wish. This solved my case so I am leaving this here for anyone who experienced the same.
