In SH4 WOP, I noticed the smoke that comes from the stacks of the various surface ships (military and merchant) is barely visible, especially at distance. I was viewing some SH4 tutorials on YouTube and noticed the smoke was much darker and more visible in some of the videos, which looked more realistic. Does anyone know of a way to make the surface ship smoke darker, or at least more visible? Is it possibly a game file change or a mod that has to be down loaded? Go to the YouTube video: SILENT HUNTER IV DOUBLE TARGET ATTACK TUTORIAL and you will see the smoke from the merchant ships is much more visible.
