difference of hull and ballast color
 

Why this difference of color between the hull and the ballast tanks, on the VIIB and C (not on the VIIA) ?

I think they were painted like that

Oui, yes of course, but look closely at the picture, I have on the upper half of the ballast a light gray different from the dark color of the hull

If I remember correctly?
The UV mapping is different.

I'll check and get back to you.

OK. Mapping is the same and the same textures are used.
Scratch that Caustics thought.

It appears to be the AO mappings. Notice the difference from the 7C on the left and 7A on the right.

Merci, very wise - I was just studying these 2 images, and wondered if I would dare to cut/paste these parts from VIIA to VIIB with photoshop...
I guess the solution is more complicated!

Just did some more examinations.
Here is the AO mapping for the 7C.
Notice the parts I have circled and pointed to!
Edit the colors to match them more closely.

On the 7B you'll find the same type parts. So edit those in any paint program.
The circled part is the upper half of the ballast tanks.
To check? Do a pattern on those upper parts with a color taken from the lower sections.
Then check in Game.

You can do some CRAZY stuff by messing with the O01 texture files!
Try placing red stripes on a few parts once.
Check the Bismark AO01.dds!

Well yes, thank you, with Photoshop I managed to darken the upper surface of the ballasts

Glad to assist!
