The back of the head in the subpart does indeed use a 2-4cyli primitive.
You have a good point, but I am concerned about the two slices of cone-like
quads which form the curves above and below the cylindrical face area (on the
front of the head these are potentially decorated also, so are omitted from the
subpart). POV-Ray will not be able to convert these conic slices so where it
converts cyli primitives to true curved surfaces, there will be a bad join
between the cylinder and the conic slice. As implemented this currently only
occurs at the back of the head.
Using 1-8cyli for the cheeks will make this bad join obvious on the front too.
What do users prefer - perfect joins or better rendition of curved surfaces
wherever possible. Most of the non-Town heads will not benefit anyway, as the
pattern extends around 180 degrees.
I suspect the real solution to this is to recode these fine detail parts to use
polygons with many more edges, but this will need greater programmatic support
for the projection of the pattern onto the prism - and create much larger part
files.

I thought I did this - there are definitely type 2 lines drawn in the centre of
the insignia quads. Does it make a difference if these are drawn before or
after the quads?

| (...) Yes, at least it makes a difference if the lines are drawn before or after the surrounding/contrasting color quads. LDraw (and LDLite) favor the earlier-drawn object, when two objects occupy the same space. Always draw edge-lines first. Steve (25 years ago, 18-May-99, to lugnet.cad.dev)
