Hacking Xenoblade X - 3D models extractable?

[Knoskoloz]

Hello there

is there any info about the 3D format which is used in XbX?
I want them mostly for Cosplay references (this was a great help for varios Xenoblade Chronicles Cosplays)

So far I found various promising cpk file chr_dl.cpk and chr_en.cpk. The file structure pretty much looks like these are the 3D models.
Example:
dl019100.camdo - most likely the vertex/polygon coordinates
dl019100.camtp - guess this is the info which material/texture belongs to which part of the 3D Model
dl019100.casmt - Textures maybe
dl019100.efp - no idea
dl019100_rig.hkt - bone rigging I guess

Sadly I have no idea how I can convert or use this files at all. Maybe someone already know/has an idea how to convert or use these files?

Thanks in advance if someone knows a bit about this
