Is it possible to change the heading (I don't know if this is the right word) of the submarine in sh4? That is, that when surfing, the bow sinking into the water and be more realistic.
I get the impression that instead of navigating moves through a flat surface.
SH3 compared with SH4 has a more realistic behavior, I think.
Thank you.
Sorry for my english, speak and write in Spanish a lot better.:rotfl:
