After updating to Unity 5.4.0f3 I can no longer bake navmeshs. Or the navmeshs might be taking REALLY long to bake. Previously I could bake terrain in a few seconds but now when I press bake if just flashes "Exporting Tiles" at the bottom right rapidly with no progress on the bar. What I've Tried: - Insuring the object I am trying to bake is set to navigation static (set everything to static just to make sure.) - Set the Navigation Area in the baking window to "Walkable." - Tried adjusting the agent size and even looked into the Advanced tab and messed with the "Manual Voxel Size." - Attempted to bake a navmesh in another Scene - didn't work. - Clearing the GICache. - Waited around 2 hours for a simple 1x1x1 Unity cube - still did not bake in my project. I haven't tried another project yet - I will allow it to bake overnight. I really hope someone can figure out what I'm messing up. I've been working on a game for almost 2 years and it would be a serious pain to have to port it out into another project or use another pathfinding solution.
