'orthographic' camera would be wise, prevents distortions caused by the
default 'perspective' camera, when making image_maps with procedural
textures.
I most often use the normal "twin", as Jan suggested. Much quicker and
easier if all you want is a better textured surface than color alone.
The HF method is best, however, if needing true depth to the surface
(albeit, usually planar).
