Still adding details. Here's a progress shot of how far I've gotten now. I'm still looking for a better base texture and an effect that barely shows up on one base texture looks exaggerated on another base texture. That's the reason for why the black lines are surrounded by very obvious white borders. They won't be nearly as obvious when I'm done.
I will be adding lots more detail before I'll call it done. I'm getting closer to how I want the surface to look, though most of the ship is still without any details.
I'm not sure how dirty I want the ship to end up being, firstly because you aren't going to run into much dirt as such in space, so scorch marks are more likely, and secondly because it's going into HW2, where the ships are built on demand, so I'm probably going to go for a "fresh off the assembly line" look for it.
I'm glad I have a copy of the old WC3 playguide for reference, so I can see where they put the panel lines on the original high poly model. Unfortunately, most of the shots in there are greyscale, so there's not much in the way of color reference. At least the front cover is in color.
Bonus trivia question of the day: Who knows where this update's headline comes from?
