Кстати, теперь там версия Торговцев № 2.
Но что то там (МНЕ) не понятно, как его устанавливать, что то надо прописывать в Campaign_RND.mis
Вот Readme.txt
The download includes two extra ships: one transport and one cargo. I needed merchants for the operational thearter of the 30th flotilla and I made them by converting British and German aux. cruisers to merchants. They come as fully independent and multi-skinned units. The download also contains roster files for British, American and Canadian fleets.

If I understand it correctly, it should be enough to add these ships to the roster so that campaign's random routine can pick the ships up using their UnitType identifier. Below, you can see a section of Campaign_RND.mis

[RndGroup 597.RndUnit 1]
Type=102
Origin=British
Side=1
CargoExt=2
CargoInt=0
CfgDate=19390101
No=1
Escort=false
SpawnProbability=100
CrewRating=0

where presumably Type=102 means a random selection of a cargo ship out of a number of available classes and No=1 means usage of the skin number 1 for the selected vessel. If this interpretation is correct then by looking through the campaign file one can find out what types of ships can be spawned for each country.

For example, I set UnitType for transport to 103 in her CFG file in data\Sea and Roster folders. In stock campaign, this transport may appear as British. But if her UnitType in those CFG files is set to 102 (i.e. as cargo), the transport may be spawned for most of the countries in the Roster directory.

INSTALLATION INSTRUCTIONS

The files in the download are already sorted in the appropriate folders. Just copy them to the corresponding folders in your SH3 installation.


Transport may appear in the stock campaign only for British while cargo may be found to carry US, UK or Canadian flags. If you want to have some probability for these ships to appear in other country fleets, you need to do the following:

a) for cargo
Copy NKGN.cfg file from the Roster\American\Sea directory to the corresponding country directory in the Roster, i.e. Roster\"Desired Country"\Sea. After quick scanning of Campaign_RND.mis I think that the stock campaign may also spawn the cargo with the UnitType=102 identifier for Australia, France, Germany, Greece, India, Italy, Netherlands, New Zealand, Norway, Poland, and Sweden provided NKGN.cfg is added to their folders (you may also change the country tag for the cargo name inside NKGN.cfg which is US Cargo for US, BR Cargo for UK, etc. if you wish).

b) for transport
Copy NPTR.cfg the same way. Change the UnitType=103 inside NPTR.cfg in the Roster directory for all the countries to UnitType=102 and also inside NPTR.cfg in the data\Sea\NPTR folder. She will be spawned as cargo.
