Hopefully, one of the expert modellers can answer this for you. Apollo Max is the only human figure I know about with all those detailed toe joint groups and parameters, although I believe there are some old animal models that may have them. This isn't part of your question, but it raises some concern that a modeller trying to add toe joints to an old Daz model might be tempted to use Anton's joint parameters to save time and effort. There isn't alot of precedent for rights in regard to joint parameters, but my belief is that we shouldn't copy them without permission.
