Archaon's bright pink glowing helmet needs to go; he has suffered from this abhorrent lighting / bloom / glow / whatever issue in Warhammer II since release.
Ever since Warhammer II rolled around, Archaon has had the pink glow effect of his helmet turned up to eleven. His helmet is fine in Warhammer I and the helmet appears to be fine in Archaon's portraits in Warhammer II. His in-game model, however, is a completely different story.
With all due respect, I can't imagine ANYONE preferring the lighting / bloom / glow effects of the Warhammer II engine on Archaon's model, especially the helmet. It looks horrible.
