Recast Informational Post

I have seen posts in the forums of people stating that the Recast navMesh was only being generated for
half of the terrain. I ran across this recently, after creating a testbed level for bug fixes and feature
enhancements. After adding the Recast resource, I noticed that only half of the navMesh was being
generated for the terrain block. I spent two evenings combing the Recast code to see if something
might being causing the issue. It is NOT anything in the Recast code! I narrowed it down to the
heightmap generated terrain block. Non heightmap terrain blocks work just fine ( at least the ones
I have checked it with thus far). Before digging into the Torque terrain code, I decide to do one more
test. I changed the block size from 1 to 2 whilst leaving the navMesh bounds unchanged. I then
clicked build for the navMesh and this time the navMesh was fully generated within the navMesh
bounds. Hopefully this info will be helpful in finding why the navMesh is only generating for half of
the terrain block with heightmap generated terrains.As well, this info may help those having issue
to decide to use Non heightmap terrains or dig into the terrain code too, and see if it can be resolved
or a suitable work around developed.
