the comand line options will be reintigrated into TH&L by the next relese, the levels can be fine tuned to match all your personal opinions, includeing no specular at all, by defalt everything is set to 1, so this gives modders the ability to have a full range of values to work with, the only thing that was realy arbitrary was the specular power value (note this refers to the 'size' of the highlight), it was set to 16 by defalt, this setting made it small enough that it was visable, but large enough that it didn't have major aproximation errors, ships with a higher poly count can aford to have a higher 'power' level.
things general look better with even a poor spec map, and the base texture it'self is at the least a poor spec map (some instances a great one, like the blue texture on the orion),
if you are testing a HTL build I would epect you to tolorate a few details that have yet to be resolved (as we are still trying to fix some major problems, look at the knossos in any HTL build for an example), other wise you have had from nearly the start the ability to tone down or to completly disable specular lighting to sute you're desiers,
if you'r too lasy to set the comand line options then I'm sorry, I can't help you. :/
