In their shipdata.plist entry add something like the following:-
Code: Select all
<key>beacon</key> <string>G001 Graveyard Marker Buoy</string>
As to model counts - you could consider making small groups of graves into single models (but ships wouldn't be able to fly between them), adding a few large asteroids decorated with small monuments dotted over their surface (in the same way the hermitage is attached to the rock hermit asteroid), and possibly reducing the overall size of the graveyard slightly.
One of the key things that affects the FPS is collision detection, this gets more expensive when objects are within 6x their maximum diameter of each other - keeping monuments small will help, but in addition I'll add a special routine to scripting so that you can add objects to an area but will try to keep them spaced far enough apart enough not to trigger deep collision detection.
