I finally found out after 2 days of tearing my hair out why my sobers 100% underwater FX mod wouldnt work with Magnum Opus . I was also getting on occasion a faulting SHSim.act file and excessive sun glare in fog and other things . some PFX files wernt being read by the game .
C:\Ubisoft\Silent Hunter 5\data\Filters\underwater in particular . After 2 days i tracked down the offending file to be
C:\Ubisoft\Silent Hunter 5\MODS\Magnum_Opus_v0_0_1\data\Misc\underwater_dis p_map
It is saved as 32 bit whereas it should be saved as DXT5
