So I was working with the terrain code to figure out how to load my 6+-megapixel terrains, and I see a reference in CTerrainSceneNode to CTiledTerrainSceneNodeManager, which is exactly what I want. But the named class is nowhere in the codebase, and forum search doesn't find me any posts about it. What's up with this lonely 'friend' declaration?
It's part of IrrSpintz where also the Terrain code comes from, but it wasn't added to Irrlicht, yet. I think there had been some posts on this topic showing how to add it to Irrlicht (maybe just copying the files and adding to the project will do).
