So you don't get the below with viewer version 2.0.1.2 ?

are you sure you're running the correct viewer executable ?
(the old version's installed menu link will still point to the installed version,
you'll have to place the 2.0.1.2 in the viewer's install folder and
run it manually, or make a new shortcut).
Invisible ships typically means that the game can't find the relevant textures,
but in this case the new 'eclipse' is using older cat file textures.
Maybe it can't find the model file itself (or you've got install interference
from your other xsp files).
For me just EclipseV2.xsp, installed with PluginManager created
PluginManager.cat/dat in the mods folder,
and also 10.cat/dat in main X3R game folder (is that expected ?) containing :
objects\ships\player\player_m3p_scene.bod & player_m3p1.bod
Body looks like a beefed up Argon Nova, but with Eclipse shields & stats.
