SimpleMoveToLocation does nothing

I’m trying to implement movement in style of third-person example in unreal 4.7. And now I’m stuck because SimpleMoveToLocation does nothing.

UNavigationSystem::SimpleMoveToLocation ( this, target )

I call this function with valid target vector. After debugging, I found out, that MainNavData == NULL and it could not be obtained from world?

What is the problem?

Thanks!

Does your level have a navmesh?

Oh, I’ve missed that! Thank you!
