Nothing to edit the skeletal animations yet. Real life is just to busy.
I did get a question about facial animations and took a few moments to look at that.
Seems they are nothing more then meshanimationdata files.
I told how to export and re-import those for SH3 a LONG time ago!
Only difference with SH4 is the way they are stored in a dat.
S3D will not give you any help until I finalize the format and create the needed steps to do it.
