Not sure what you mean by huge blackish spot. Could you take a screenshot for me?
Concerning the new hulls, there still is chipped paint, the effect is just different and far less apparent. I may change it back at some point. What I did to "change the color pallet" was basically polarize the colors. The outcome is hard to explain. Basically it adds more variation of color. If you compare the earlier hulls with the new, the effect is noticeable. But it also comes at a price, as it can have a darkening or lightening effect to some colors. But it also gives a sort of Polaroid Picture effect, which I thought was pretty unique.
I'll try and fix those dark spots. I think it's just a victim of color replacement. Looking at t000 now, looks like the hulls were the only textures to have that strange outcome. Really the textures that got the most out of the replacement were the terrain. That's why I decided to go back and see if I could do the same with the hulls.
Anyway! Yeah, I was just experimenting. It's cool that you brought that to my attention. Wouldn't have known, otherwise. Thanks for telling me! I'll get on it :D
