I don't mind personal use, but I'm going to quote from the Archon's readme:
KRS Incursor Cruiser Mod
Please do not alter OR redistribute
the contents of this mod.
The Incursor Cruiser is part of a
larger WIP project and should not
be included in any compilations or
ship / weapon packs.
Note the "alter or redistribute" portion - Incursion is still WIP (and barely at that), so I'd appreciate it if ship graphics (even spliced/recolored) were not used in other mods. Personal use is one thing, if it's just staying on your drive, for your game, but please do not distribute it publicly.
