Hello everyone! Can someone explain me the .CHKN File type (maybe via pn or better per discord) ?
What is a CHKN?

@xChaoz
Are you familiar with the ZIP archive file type?
A CHKN is just a folder full of CAL3D assets, zipped up, and then the "ZIP" extension replaced with "CHKN".
CAL3D assets are files that can be loaded into IMVU via IMVU's CAL 3D engine.
These assets include:
Animations - XAF's (XML Animation Files) or CFS's (Compiled Animation Files)
Morphs - XMF's (XML Morph Files) or CMF's (Compiled Morph Files)
Skeletons - XSF's (XML Skeleton Files) or CSF's (Compiled Skeleton Files)
Material References - XRF's (XML Reference Files) or CRF's (Compiled Reference Files)
Textures - image files (example: png's, gif's, jpg's, or tng's)
Index - (a single index.xml file containing product information)
Json - (a single json type data file containing developer information)

Already wrote to you via Discord and this is what I've already figured out - it's a ZIP File but I ask myself if it's enough
to create a ZIP File with the files needed by IMVU Creator and rename it to CHKN. All CHKN-Files should include
- index.xml
- imvu-internal.json
- ...assets files

Yes, that is enough. IMVU inc did not create their own compression / archive algorithm. All they did was re-use and re-name a ZIP. Nothing fancy nor unique.
