AI voxel navigation streaming #1475
Description
At the moment AI navigation Voxel requires the user to delimiter a volume where the voxels will be generated.
I propose the idea of having a streaming voxel volume, similar to how grass and props are loaded, the voxel volume would be streamed, this would allow automatic AI navigation without user intervention.
Voxels could use a LOD system, similar to the one applied to VXGI, where close voxels are finer and more distant ones are coarser. Maybe the voxel structure could even be used for both systems if it makes sense to do so.
It would nice if when a dynamic object moves, the voxels in the affected zone could be invalidated and recalculated without recalculating all voxels.
