Even I set Project Settings -> Navigation Mesh -> Runtime Generation to Dynamic, but it doesn’t work.

When visualize the Nav Mesh at runtime, the three Characters of obstructing did not modify Nav Mesh.

it doesn’t work because you need to activate the affect navigation mesh and also it’s not a good idea for alot of ai’s

Thx for your suggestion! How to activate the affect navigation mesh?

There is the detour AI crowd controller. You can try with that. Just use the detour AI crowd controller instead of the normal AI controller.
