Hope it works out
I never know how much experience someone may have with computers/modding......so I usually try to explain things as if you're starting out. Some one else may read this post and say.....Oh, I didn't know that!
The OTC "Names.cfg" file
may work just fine with RSRDC v390. I know RSRDC usually adds ships to its mod. The Names.cfg that's in
that OTC download
is RSRDC compatible (although, I'm not 100% sure about v390).
One thing you may run into is RSRDC changes the "UnitType" on a couple of its ships. Because of this, there may be a conflict. A way to check is to run the "Museum". If you can access all ships/planes in the Museum while just running RFB v1.4 and RSRDC v390......then add OTC for RFB 1.4, and there are no CTD's, you're OK. If you get a CTD after adding OTC, then you'll need to track down the particular ship/plane in OTC and change the "UnitType=" figure to whatever RSRDC is using.
As a general rule, looking at the Museum ship/planes is a great way of checking game assets to see if they are functional or not. If they don't fly correctly (no sound, or they crash/sink after a short period), or cause a CTD while shown in the Museum.......they will do the same while in-game.
