Remember the new version isn't the end all. I've put on hold trying to get the rest of my ships in for the mod, simply because I have too much real life work to get on with. No doubt there will be balancing issues with the new mod version, bound to be some exploits and so there will be patches etc. If an auto-update system were implemented, it would be far easier though..
@ Xing: Upload what you have on developer board submission forums. Then we can check the files and make custom hitboxes. They also might go with resized vanilla ones. Unfortunately there is none which fits the fighter shape, while destroyer and BC seems good to go using resized vanilla ones.
If you could provide the models coded, means shiparch.ini, goods.ini and infocard in .txt file format.
Simply use the general templates Igiss has posted on dev board. Values will be changed in balancing process anyway.
Most important is to have something to implement and to balance. Hitboxes can be made later.
