Another thought.
What if, perhaps, the animated textures for the DM and the Organian are mission based? Both only appear in specialized missions, unless you've editted your shiplist to allow for there use in any mission.
I tried putting an Organian in a mission with FMSE, and it would load into the game, but with no texture, thus, invisible - as the dummy.mod does not have any registered textures to it. It also was stationary. I only found it by hitting Target view. I could target it, shoot it, tractor it and move it - albeit, very slowly. I think the game was registering that the Organian had allocated power to movement, but after examining it's shiplist entry I found it was lacking several key features that standard ships use to allow for movement, sensors, tractors and weapons. Interestingly enough, the Black hole/wormhole/singularity doesn't maintain it's gravity affects either with FMSE, as I placed one on the map for a reference point.
Can the API code, used to build real custom missions, be used as the basis for an 'add on' file that works similar to the model.siz file ( whether it be a .gf, .txt, or whatever...), allowing for the assignment of dummy.mod to player ship models, and assigning animated textures to these points? Any programmers out there?
Something to think about ...
