Don't let it get to you bud, we are nice
just trying to guide you in the right direction.
Obj files are generally what gets turned into a pdo.
Starts from a model file OBJ being the main one, but pep now supports other formats.
Then they need to be unfolded and saved as pep.
Just keep checking that link I gave you and if you are patient someone will likely unfold the OBJ files and you will have your pep.
you could try your hand at unfolding, but thats a whole other learning curve.
