Is there a shortcut to setting a nav mesh?

Instead of positioning and scaling a nav mesh. Is there any easy way to set a nav mesh to encompass an entire level?

yes. Its called nav invoker

You place the nav mesh but set it to use invokers so that it isn’t constructed across the whole map (above 10km square it would take forever to build the nav).

The invoker is instead added as a component to the AI, and basically builds at runtime around himself in a limited range.

Many tutorials out there on how to set this up.

Not sure on how it works with nav links and so forth, but I doubt its an issue.

Thank you i will look up nav invoker
