(I completely misunderstood the video by Rga_Noris)
Now my asteroid loads properly in PCS2.

Now onto this threads namesake: If I understood Bigchunk's videos and the wiki properly, I simply have PCS2 calculate the moment of inertia and save as *.pof, then add it to the mod folder's \data\models\ directory, then setup the modular table and mod.ini files, and activate the mod in the launcher. When I did that, FRED didn't have it in the drop-down list (
log here). The log doesn't look like FRED read the modular table but I wanted to make sure, so I replaced my *.pof with a copy of that of an asteroid from the official release and did the same for its textures (essentially making the mod create a duplicate of that asteroid under a different name), but that had the same result (
logged anyway). So it seems like either my mod.ini or modular table has the issue. Currently, these read:
[launcher]
modname = Asteroid Base;
infotext = New ship model
author = ThePsuedoMonkey
[multimod]
primarylist = ;
secondarylist = mediavps_3612;

The modular table was copied from an asteroid in the ships.tbl from Diaspora's R1_core.vp file, with my changes shown in yellow. The wiki implies that its filename must end with "-shp.tbm", which I have done, but the other caveats mentioned there shouldn't apply since Diaspora uses FS_open 3.6.13 and the wxLauncher only allows one mod to be active, even if I had any that modified tables (right?).
(sorry if my error is as silly as last time...)
