Well, yeah, you don''t really need maps for EVERY object in the scene... You can have some algorithmic way of determining the heat of a ''non-heat-generating'' object by simply using a blue texture with some noise added in to break up the monotony. Now, for heat generating objects, I believe you would need to do it manually. Otherwise, how would a computer know that a human''s eyes are ''hotter'' than their feet? And to fake this, I think it would still be really hard to pull it off without some artist intervention.
