Something I should have mentioned the first time: various amounts of
'crand'.
As long as you don't animate the helmet it should be fine. Trouble is,
you have to have light on all sides so as to cover all parts, at least
dim lights, to keep both normal and finish on all parts of the object.
If this isn't done just flat, textureless places will appear, lacking in
any normal or finish.
