A month or so ago I had a problem with one of haptek's programs.
After a couple of emails i was put onto a tech.
Eventually everything was worked out.
While talking with him,
THE FOLLOWING WAS WHAT I SAID.
I would love to put my putty heads on the full bodies & not have them still look like the original head.
THIS WAS HIS REPLY.
Its possible that in the future there will be a release of People Putty that will allow you to manipulate full body characters in the way you mentioned.
I wouldn't hold my breath waiting for something new.
As far as i can work out nothing new has come from them in a few years.
Like the saying goes,
IF IT AINT BROKE, DON'T FIX IT
