I was planning on making Tutorial videos but I just don't have the time now because of my studies.
EDIT: I scrapped up some time and found my old extracted files from the PS1 Demo Disk 1 of Abe's Oddysee! I have all the .lvl's and they come with .OVL's as well.
A quick look inside R1.OVL reveals this:
Unfortunately, the .cam files can't be converted...they are using a different compression or something (probably because they're ps1 files) but the animations all work when converted.
