Detour - Loading an entire continent (800+ tiles)

[Tanaris4]

All-

Just curious from those that are using recast/detour - is it possible to load ALL of azeroth into memory? Basically so that I can query a super long route? Right now I'm unable to as I'm limited based on this:

	// Init ID generator values.
	m_tileBits = dtIlog2(dtNextPow2((unsigned int)params->maxTiles));
	m_polyBits = dtIlog2(dtNextPow2((unsigned int)params->maxPolys));
	// Only allow 31 salt bits, since the salt mask is calculated using 32bit uint and it will overflow.
	m_saltBits = dtMin((unsigned int)31, 32 - m_tileBits - m_polyBits);
     
	if (m_saltBits < 10)
		return DT_FAILURE | DT_INVALID_PARAM;

I know that I will need my max polys to be much larger than the below.

        _navMesh = dtAllocNavMesh();
        dtNavMeshParams *params = new dtNavMeshParams();
        params->tileWidth = GRID_SIZE;
        params->tileHeight = GRID_SIZE;
        params->orig[0] = -(32*GRID_SIZE);
        params->orig[1] = -(32*GRID_SIZE);
        params->orig[2] = -(32*GRID_SIZE);
        params->maxTiles =  850;
        params->maxPolys =  1000;

Thoughts?

You can either change it to use 64-bit poly identifiers or patch that if condition (the salt is only really needed if your tiles are reloaded a lot - it's useful for tiles that change).

Perfect thanks - I was debating patching but wasn't sure what I would break.

I'll switch to 64-bit IDs

Edit: Switched to 64-bit and it's working well. I'm using these parameters:

        params->maxTiles =  1000;
        params->maxPolys =  65536;

Just curious, in theory, I *should* be able to generate a path from IF to SW, right? I'm trying it now but I only get about 30% there and it stops. I get a total of 108 waypoints.

I think the problem may be that I created ONE mesh per ADT, vs splitting the ADT into 16 tiles. But not sure if that would cause this specific problem. (I realize some polys may have been lost by doing one mesh per ADT, so it's just a theory). Does that sound right? Or could it be something else?
