Hello mate!
First, congratulations. You have modelled beautiful meshes, and the project is fantastic! Everything is perfect, from the water to the ligh system of the scene. I use Blender too, but I'm not so good at it...
Anyway, it's an awesome project and I think that you are developing it in a really good way!
I'm a fan of the cold war's subs, especially of soviets one...
Just one question: do you use c++ or python?
Good evening and long live Subsim!!!
(Ps: sorry for my bad english!)
