Problemm with the creation for biger nav meshes

[Andy90]

Currently its not possible to create nav meshes wich are bigger then 8x8 cells.

I see an error printing in the console, but I don't actually see any problem with the generated navmesh. Do you?

Yeah, it will not work within the game it self. You can test it within the project i uploaded a few days ago. Even if you scale the coded version bigger then 8x8 it will not work anymore.

I added some more debugging messages and whenever I go over 8x8 I get errors that say "operation ran out of memory". This occurs no matter what I set tile resolution to...

[Andy90]

well this sound not intended  i dont think a nav mesh needs 64GB Memmory

I think this is being caused by this strange calculation I needed for the creation parameters:

		int tileBits = NavMesh::rcMin((int)NavMesh::ilog2(NavMesh::nextPow2(tw * th)), 14);
		if (tileBits > 14) tileBits = 14;
		int polyBits = 22 - tileBits;
		params.maxTiles = 1 << tileBits;
		params.maxPolys = 1 << polyBits;

I have submitted an issue to Recast here:

In the process of explaining the problem I think I solved it. Update is incoming later today.
