I have implemented the Tier-2 subdivision code.<\/p>\n

I did have to duplicate the code from Tier-1, which is messy, but I can optimise this later. I can now cull the long-distance nodes in 64-bit space, then further subdivide the terrain in 32-bit space.<\/p>\n

The terrain still looks quite jagged, and I need to spend some time smoothing it. The texture painter is also not working, and there are some other bugs and issues to fix as well, but I am making progress.<\/p>\n

The next goal will be to translate the 64-bit node position to 32-bit, to eliminate all 64-bit values from rendering completely.<\/p>\n

The below images are quite small and difficult to see (since I have scaled the terrain down to 10k), but these images show multiple LOD’s rendering at the same time:<\/p>\n
