There are a total of 96 models included here. There are 3 sizes, 8 orientations, and 4 height placements, for a total of 3x8x4 = 96 variations. There are so many I have to split it up into 3 zip files.
The files are organized in 3 levels of folders. The first level folder is just "ladybug". Under that folder, you get 3 subfolders, one for each size (.5x.5 = small, 1x1 = medium, 2x2 = large). Then under each such folder, there are 8 subfolders corresponding to the orientation (south, southeast, etc.). Finally, under those folders, there are 4 3DS files named "ladybug00", "ladybug10", "ladybug15", "ladybug20". These are the placement variations. The 00 sits on a floor, the 10 sits on top of a normal-height wall, the 15 sits on top of a 1.5 wall and the 20 sits on top of a 2.0 wall. Hope all this isn't too confusing.
Obviously to use them in your own levels you'd need to copy them into your own folder and rename it.
The dead spots for the 1x1 and .5x.5 is just the center as expected. For the 2x2 sized ones, the deadspot is always the upper-left tile.
PM me if you have any questions regarding this. Also, if you need some other orientations, sizes and placements (say, having it crawling up on the sides of a house or something), just PM me and I'll see what I can do.
Those of us who are making the models appreciate how much work goes into them.
