I don't think this has been done before surprisingly, so here are 45 supporters to add to your tracks !

I used models by Quaternius that you can find here for more than half of them http://quaternius.com/?i=1, then made some more interesting poses myself.

There are 4 folders : Walking, Sitting, Standing and Flags. The 2 smaller flags display the image of the club.

I made a small tool to help me generate all the file needed for these items (meshParams), so if you wanna do something similar yourself but don't want to create all the nadeo importer files by hand, feel free to ask me and i'll send you the tool (very primitive tho).

They are pretty light, so you can use them all in your track without them eating all those 2mb.
