I would also like to know the answer to that question.
Transperancy of retopo object dose NOT effect the back face culling issue.
Why would I want to see the back faces of my retopo object anyway?
Also my high poly reference mesh is getting hidden once it's on top of the view of the the retopo object,
which in some place, because of the mesh shape, it's the only angle you can work with, but than you can't see the reff mesh so you can't retopo!
And how is this topic solved exactly? no answers here what so ever is this for real?
3d coat is a nice program but since the UI is so bad and it has so many glitches the least you can do is give some decent support.
As a paying customer I must say your support is horrible! I never got any answers for any of my problems.
Topic solved, yeah right.
get your act together 3d coat devs seriously.
