Still toying with my navmesh algo workflow, I though of using Blender (or other 3d soft) to build edit navigation mesh. And… Blender 2.6 will most likely integrate Recast navigation mesh generation, so thumb up for Recast for Unity3d Indie (all working plugin require Pro version, because it use DLL)
But to achieve that I needed to export all geometries from my scene and import them into Blender. So I build an Scene → Collada (.dae) exporter.
It support only mesh hierarchy. I’ll post it on my Google Repository for everyone to extend (for cameras textures pretty much everything else than geometry).
I’ll reply here when I’ve uploaded my source.
