Open Silent Hunter 5\data\Scripts\Menu\
IO_StrategicMap_Settings.py with notepad and you'll find there following lines...It's pretty much self explanatory from this point , I'd say...
Code:
###### IO_Strategic_map options ############
#+++++ specific IO_Strategic_map items ++++++++
#
# is the dripped visible?
# change below to either True or False
IOSMDrippedEnabled = True
# is the NavMapSeal visible (stam)?
# change below to either True or False
IOSMNavMapSealEnabled = True
# is the Plastic Texture visible?
# change below to either True or False
IOSMPlasticTextureEnabled = True
