Multi-grid path finding???

Unity Engine

Hello,
I was wondering if there is a way to put two or more path finding grids in one area, so that the characters that can do things (like open up doors) verses the characters that can not open up doors would use a different path finding grid. If not, then is there a way that certain obstacles would only apply to certain nav mesh agents?

Thank you

Try using off-mesh links. You can activate and deactivate links (at doors and such) before settings a target destination of a Navmesh agent, to control whether it will attempt to use the door or not.

I haven’t tried it, but I’d do the following:
On agent with restricted motion,

  1. Disable relevant off-mesh links on the nav mesh
  2. Set the target position and wait for the path to be computed
  3. Re-enable the off-mesh links

I think you can use Navmesh Layers and costs
