I've noticed while looking at the .blends of the tracks in the media repository that many of them are not finished. For example, the source .blend of Gran Paradiso Island is missing all the ferns in the rocks, and the source of Cocoa Temple has almost no palm trees.
It also seems that not all of the library objects are in all the repositories. I ran a file comparison on the objects and made a list:
Library objects in stk-assets but not in media repository:
- stklib_conifer_a
- stklib_olmec_a
- stklib_pumpkin_a_mesh (not sure if this is wanted anyway—there's no texture in that folder)
- stklib_quetzalcoatl_a
Library objects in media repository but not in stk-assets:
- stklib_barrier
- stklib_paperAsiaLamp_a
- stklib_usSignMerge_a
- stklib_wilbertCam_a
Also, stklib_bambooTorch_a exists in both the lamps and buildings folder in the media repo, but the one in buildings is just a solid cylinder.
This is very disappointing, since I rely on the .blends of the tracks to make sense of a lot of the track-making things that aren't documented, and other track makers have to be able to rely on things in the media repository being visible in-game.
