Try this: here is a copy of my mdlnames.dat file with Usio's (most of em) ships already on it. That may help with the Mission Builder issue. As for how to make them default ships. you can place the contents of the default ships in a backup folder and drop the contents of the Usio folder into the default folder. Rename the cfg file to read (example...)
[fltsim.0]
title=CV Shokaku
sim=shj_shokaku
model=
panel=
sound=
texture=
...and change the MISC_DATA unit family and category to the correct ones for that type of ship - Usio always uses 7/13 to make all of his ships carriers.
[MISC_DATA]
unit_family=7
category=13
allegiance=4
min_speed=0
cruise_speed=55
max_speed=55
entered_service=12/1/41
I would save the default ships as they are and just place Usio's in the SHIPS folder. There are times when you might not want to use them because they are very demanding on framerates.
Be sure to grab some of Colin's ships, especially the Essex class carriers.
I was Wondering why some of the ships are showing up as Carriers in MB. Now I know. Thanks for the info. Blondi:cost1:
