The existing shielded-Lucifer model consists of a really inefficient shield mesh (lots and lots of coplanar polygons), which was made for the
Lucifer and then ported to VA's high-poly one. Needless to say, it doesn't fit. The protuberances are not covered, and the entire shield is basically too small to contain the hull. So (per request from Scroll) I made a new shield mesh. Download can be found
here on FSMods.
For use: open your mod's Lucifer model in PCS2, go to "shield", press "load" in the top-right and select the DAE-file in the download. This will import the improved shield onto your model. Don't forget to save afterwards.
