-- 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).
