the updated Mei Lin 6 shaders were indeed submitted to DAZ3D long ago (it'S been actually three weeks now).
We have no idea, why they weren't updated - they also don't reply to our e-Mails and private messages anymore, since we informed them two times now via mail and PM that the ML 6 shaders were updated and that they please update their files.
The Sebastian and Bentley hair shader updates are still being worked o,n since we wanted to accommodate for all the changes that users suggested, whilst working with the Genesis 2 and Millennium 4 female shaders.
We will try and get them out there before Christmas and should soon deploy them to our testers.
Just a little longer

Thanks for your patience, but we'd really like to get rid of all the bugs this time and accommodate for all changes (changes made in pre-release 4 and user suggested changes).
Hope this clarifies things.
Kind regards
Noel
PS: As you can see it becomes increasingly more difficult for us to provide all of you with a decent quality version of our shaders for DAZ Studio, since we now not only have to fight against a lack of communication with the OctaneRender plug-in developer for DAZ Studio, but also the creators of DAZ Studio themselves...
