This is correct. You absolutely must model locally and position with a transform for databases of any significa

Hi Shayne, The coordinate system produced by VPB is a standard geocentric one, like you described. The actual vertex positions of the terrain tiles are centered around a local origin and positioned using a MatrixTransform. I'm not a shader expert, but I think that the gl_vertex.xyz is actual val
