The seam problem:
I read that is a problem with each scenenode LOD, but I really don't know how to play with this.
yes, the LOD can bring problems, set the maxLOD to 1 when creating the terrain...
But I think it's because of the terrain bug I solved in the "Bug Reports" forum !!!
Write some text on the textures and apply them to the terrain, you'll see...
