Hey everyone, so I am having quite the problem with my navmesh and how it’s building. I am building halls for a hotel in a VR project and the geometry I am working with is extremely simple. It keeps building in areas I don’t have the geometry and it doesn’t build in areas where there is geometry. It also keeps elevating my pawn higher than the rest of the mesh when there’s no height difference in the geometry. A little background, this is a VR project and I have watched a lot of nav mesh videos and read the documentation and I still can’t tweak it enough to fix the problem. Any help would be fantastic. Thank you so much.
I had a problem like this before, and this is how I fixed it. Go to whatever static mesh that the NavMesh hits, or is on. Click on the Static Mesh, go to the Details Panel of that mesh, then UNcheck the little box, so that the particular Static Mesh won’t affect your navigation. I really hope this helps!
After that you will probably have to rebuild paths to fix it! Go up top in the UE4 Editor and click on Build, then click Build Paths, just in case you didn’t know. Good Luck!
So unfortunately it didn’t work… 
Make sure to do it on ALL of them that come into contact with the NavMesh Volume, then save all, then click on Save at top also after doing this for All of them, then Rebuild Paths. It should work.

Update, it worked but my nav for my VR pawn is a little wonky and not working correctly. It also won’t let me go to places on the map where the mesh is built.
Is just happening in doorways, or open areas also? If it is not allowing AI through the doors, then you will have to add in a Nav Proxy Link in every doorway. If it is happening out in the open areas, I would suggest rebuild the lighting, and then save it. I hope it Helps you! I will link a video on Nav Proxy Link that will help you if that is a problem you are having.

Not neccecarly. It’s my VR pawn and even though it shows that the nav mesh is there it wont let my pawn move
I haven’t dealt with VR much, so maybe this can be of more help than I can, hopefully! hope it helps!

Yeah this is the video I always fall back to when I’m fixing things. Thanks though.
It’s just frustrating because it shows that the nav mesh is there but when I test it with the VR pawn it can’t move. I just can’t imagine that that one setting messes it up that much
