Hi all

I’m working on a level with massive moving vertical platforms, the issue I am having is that the navmesh won’t follow the platforms when they move up and down between levels.

Is there a way to update the navmesh setting at run time in blueprint ? So they are dynamic whilst the platforms moves up and down but once stopped at a level changing the nav mesh back to modifier only.

You could try using navmesh invokers for this
