I wasn’t able to reproduce this issue. Which version of engine are you using? When you place Nav Mesh Bounds Volume in level, do you see Recast Nav Mesh appear? If you go to Project Settings > Navigation System, what is Dirty Areas Update Freq set at? You mention your static mesh being a corridor… could you either provide that asset here or show me an image so I can recreate it? Thanks!
Yeah… this is still a problem. Was following a tutorial and couldn’t get it to build. Then saw this and moved it back and forth, pressed P a few times, moved back and forth again , and then it finally showed up.
