[Solved] Need help with nav meshes.

Is there a way to manually adjust a nav mesh bounds?
i get some areas in my meshes that are broken and cause my zombies to stand there running in place and it happens at door ways and a few other places. here is a screen of what is happening.
its not on all doors either. just a few and it is really annoying me.

there is a nav modifier volume. also check collision on meshes.

thank you i’ll check that out. i checked the mesh and its good. since it does not do this in every instance of this same mesh

thanks that worked!
