+-- Bumpmapping and Parallax Occlusion

+-- This node has a normal map which corresponds to a pyramid with sides tilted
+-- by an angle of 45°, i.e. the normal map contains four vectors which point
+-- diagonally away from the surface (e.g. (0.7, 0.7, 0)),
+-- and the heights in the height map linearly increase towards the centre,
+-- so that the surface corresponds to a simple pyramid.
+-- The node can help to determine if e.g. tangent space transformations work
+-- correctly.
+-- If, for example, the light comes from above, then the (tilted) pyramids
+-- should look like they're lit from this light direction on all node faces.
+-- The white albedo texture has small black indicators which can be used to see
+-- how it is transformed ingame (and thus see if there's rotation around the
+-- normal vector).
