Summary
I have an aim training map (Shinobi Zero Build Mastery Map: 4472-5388-8581) with a healthy player base that works great, except for in the new area of the map that I’ve added. I have added a new dungeon crawl area that includes new creature spawners, guard spawners, as well as custom NPC spawners. The problem is NavMesh is not being generated correctly 75% of the time - which causes all AI to just stand still, or craeture spawners to not spawn any enemies. It’s incredibly inconsistent, and the NavMesh is usually generated after the player is eliminated a time or 2.
I have tried everything I can think of:
-I have moved the entire new area to be closer to the center of the map (0,0,0).
-I have disabled all AI spawners across all other parts of the map to ensure its not a ai memory issue.
-I have changed the physics material on the static mesh to fortbuildingmeshphysics instead of fortstaticmesh.
-I have toggled the navigation options in the details panel for the static mesh “can ever affect navigation.”
-I have scaled down the static mesh to a default 1:1:1 scale ratio, and turned on grid snapping with perfect snapping from the 0,0,0 coordinate.
-I have tried different static meshes for the floors from new galleries like Lone Wolf Lodge.
-I have tried eliminating the player early on in the new area to hopefully generate a new NavMesh upon spawn.
-I have tried enabling guard spawners at game start in the new areas to try to generate the NavMesh early on.
-I have made sure structural support is enabled for meshes.
If you watch this section of the video, you will see how the navmesh is inconsistently generated before the player dies vs after the player dies: https://youtu.be/OpfQZ3hC970?t=448
If you watch the whole video you will see a detailed explanation of what is happening and see that the navmesh rarely generates in most areas, until you reach an area where it happened to have generated, then die and it seems like all navmeshes are then generated.

Steps to Reproduce
You can watch the reproduction here: https://youtu.be/OpfQZ3hC970?t=448
But if you want to reproduce it yourself, do the following:
-
play the live version of my map: 4472-5388-8581 in PRIVATE mode.
-
Enter the main lobby, turn around and look on the wall for a small button that says “Dungeon Crawl Alpha”. Press the button.
-
Enter the cave, you’ll notice no creatures are spawning. You can press a small button on a rock right in front of you to skip past this cave section if you’d like - or just continue to follow the torches to the next section.
-
talk to the npc at the campfire to select a player class and open the door to the dungeon. You’ll see no creatures spawn but you’ll probably see 2 NPC guards standing still. Capture the zone. Go through the next door to see a bunch of AI standing still. Run past them or eliminate them. Break the rocks in the path in front of you to drop down to a new area - these guards actually move. Die to them, respawn and there is a good chance that all AI are now working.
Better to just watch my video explanation though, as this seems to be a pretty unique issue with my map: https://youtu.be/OpfQZ3hC970
Expected Result
Expect all guards and creature spawners to function and generate nav mesh
Observed Result
Guards and creatures rarely spawn/move because navmesh is not being generated.
Platform(s)
PC and Xbox both tested.
