I use the type 2 approach in LDCad, but it will still cause a 'crumbled paper' look due to the fact the pattern breaks the curve of the sphere.
This because all polygons are flattened to the n facets resolution of the sphere and thus causing slightly different normals for their vertices.
You could prevent this (i think) by using a facet resolution for the whole sphere that matches the smallest detail of the pattern. But it would inflate the part size (primitive count) considerably.
Alternative is off course using a texture.
