In my msh folder, there are all the .tga files and .msh files that come with the download. But when I clean/munge/load, the cape doesnt show up (only the model).
This kind of cloth is actually part of the unit msh and not an addon, just enabled by ODFs. Addons are both incorporated and enabled by the ODF, like Dooku's cape for SWBF1. Post your whole unit ODF, you probably didn't call the cloth ODF under properties.
