Thank you for reporting the issue and providing the model!
I believe I've reproduced this issue in Recast itself using RecastDemo. I'll need to investigate further, but we might need to:
a) Check if this is fixed in the latest Recast versions.
b) If not, consider upstreaming this issue.
RecastDemo also fails to generate a navmesh with cell size and cell height both set to 0.2 and a slope angle of 60. I'll need to confirm if this failure is for the same reason.
Interestingly, these variations also succeed:
- Using a "Walkable Slope Angle" of 45 instead of 60 (45 is RecastDemo's default)
- Using a cell size of 0.3 and a cell height of 0.2
Here's the model as a obj, RecastDemo doesn't support gltf/glb - big-terrain.obj.zip
from recast-navigation-js.
Looking at the buildContext logs, this appears to be the root cause:
This looks like a limitation of the watershed partitioning method that recast-navigation-js
uses for it's default solo nav mesh generator.
If you're interested, you can read more about the different partitioning options here: https://github.com/recastnavigation/recastnavigation/blob/cd898904b72a300011fbb24d578620bafa08ef2c/RecastDemo/Source/Sample_SoloMesh.cpp#L522
from recast-navigation-js.
The general advise I've read on recast's google discussions + github is to create tiled navmeshes for large maps.
That said, the tiled nav mesh generator also appears to have some bugs. Generation succeeds, but tiles aren't connected.
Let's at least leave this issue open until tiled nav mesh generation issues are fixed 🙂

Fix for tiled nav mesh generation incoming 🙂
from recast-navigation-js.
v0.10.2 will be released shortly with the tiled nav mesh generator fix, and navmesh.isaacmason.com has been updated now.
Let's convert this issue to a discussion, I think others will benefit from this.
LMK if you have any questions!
