Does an OGL Version of D6-Legend exist?

I’m wondering. I saw a few references that aside from the normal D6 also D6 legend could be OGL. (d6that is success based and 5+ is a success).

When I searched I stumbled only over one single book there that didn’t seem very official and deviated greatly from d6 legend as it had 3+ as a success.

So my question is: is there a OGL variant of d6 legend?
