 The Tex Coords from XYZ node generates world space texture coordinates for the shader or function nodes assigned its Main Input.
-That is, it returns the current altitude of a given sample point which more than likely has been modified by displacements, such as a Power fractal shader, from its original position on the planet’s smooth surface.
+Historically, this node was first written to compute texture coordinates, and later as the need for surface normals became apparent the Compute Normal node was written.  Finally, the Compute Terrain node combines the functionality of the Tex Coords from XYZ node and the Compute Normal node into one node.
-Without this information, certain shaders within Terragen such as the Surface Layer shader, might not have the correct altitude values at render time.  Click [[Render_State|here]] for more information about an item’s render state.

-Taking the default Terragen project for example, if displacements occur after the Compute terrain node in the Terrain group then it’s possible that a Surface Layer shader providing colour information for the terrain might not have the correct altitudes to apply colour or constraints.
