Super, your help is welcome. I notice for the dark green. You have to understand that my main preocupation is: what could we see from the exterior once the flooding holes are open. What is visible and what is not. That's all. Henceforth the questions are clear, I'm going to update the model and come back with the corrections. Time to dive again.
Thank you kamerad and bonjour de Paris !
PS: btw, thank you again for your report, to have pinpointed the problem and help me make this model the most authentic in greater objectivity. Au dessus c'est le soleil !
