Step 5. is the one you
must learn if you are going to mod ships, subs, guns or anything like that in the game.
It is the 'hard' part but not so bad once you learn how. Remember I am a beginner and the one that can't get his ship working in a career mode..


.
Copy a sub's dat file to a working location and copy your ships .dat to a working folder so you can practice without messing stuff up. Everyone makes mistakes.
Open Silent3ditor and open the sub's .dat file. find the front dive planes, and "export a chunk" with the node, give it a name so you know what it is. Save with the header, it will ask. Or you can number 'dive plane 1' diveplane2 etc. when you have all the parts of the dive plane exported. Open the ship's dat file and "Import chunk" for each one in the order you exported them.
Do the same for rear dive planes and torp tube doors. You need at least one torp tube.
When they are imported you will see a place for parent ID, put in the ID of the main ship node.
Then you do the same for the three items in the sim file but make sure you use a working sub. Don't use the ship or another working ship because they may have made changes to some stuff that won't apply to your ship and you will get messed up.
You really do need to learn this if you are going to do the 650 ships you listed. (Just picking on you). There is another way but it means importing the entire .dat file and then delete everything, or delete everything and then import what is left. But to learn I think you should do the export and import parts then you will have an idea how things go together with parent IDs and child nodes.
Just make sure you get each piece of the item by opening the 'tree' with the + sign at each item that is in the same node as what you are exporting. Then compare the sub with your ship when you get done each part. When everything is done and linked together properley then you can remap IDs. I don't remember if the import assigns a new ID or not, but if it is the same as the sub it can cause problems.
I will try to help when I can but I am right in the middle of something right now.
