Suggestions for Flying AI in procedural environment?

I have a map that is divided into chunks which are placed procedurally. My player and AI can all fly (think Descent-like 3d shooter where you can move up/down/left/right while flying).

Would it be best to manually place all of my points around my ‘chunks’ and use a Point Graph, or would Recast Graph be able to work this out somehow - since the player/AI shouldn’t really be walking ‘on’ the floor, but only moving in the space between walls.

Currently, I only have the freebee version of A*, so i can’t test out RecastGraphs. I’m thinking the point graph would work fine, but it’s going to be kind of a bother to place all of the points as some of my level chunks are rather large. (i.e.: 100s of units wide/deep)

Hi

This system currently does not support pathfinding in 3D space (except by using point graphs). Pathfinding in 3D space is usually prohibitively expensive both in terms of memory usage and CPU power.
Could you explain a bit more what you want to do?
