I've taken a look at nclod and nct some weeks ago. I merged both into nebula
tree,  got some results - meaning rendering on screen - , made mangalore viewers
but nothing that can actually be used into a project. Mostly huge issues with
shaders. Since I want opengl/glsl, I moved to this "problem" first...

in ncterrain2 I noticed some crash without been able to solve the problem. It
seem it has something to do with the lod/mesh selection. well, let's say I gave
up....

fist you need to compile terrain data/map that not actually into nebula.
nclodterrain  need its splatterrain shader too, which doesn't work very well
either, so in two world : Have fun !!!!

I can post my (crappy) code somewhere if this might help...

I where thinking about use this code as background resources and write a new
terrain from scratch...

BTW : this is why we need a forum : I already reported some of those bugs you
spend/wast time on too...
