I was able to bake a standard navigation mesh in Unity but it only works sometimes. It works when i add a new mesh renderer to the terrain and re-set to static the terrain . I can't also select the terrain with the editor. Bug or i'm forgetting something? is it because the invisible children of the terrain are being generated as non-static objects? If so, Is there a way to make them navigation-static from birth? [EDIT]: i coudn't find information about this ( in documents or forum ). Also now i recall saving a scene where the Terrain Volume was static and finding it the next load as non-static. [EDIT2]: I read some people think the problem was the scale of the terrain ( it was on RAIN navigation mesh if i recall correctly) but here it's not the case, as the terrain you see in the picture is 3 times bigger.
