Bill,
While I can't speak for everyone else, I have found that Haptek does not nor will not run on my Windows 7 64 bit computer. It was a paid version that I've had for many years and simply wanted to transfer it over to my new computer.
I will say that Jack, at Haptek, was quick to answer my emails to him even though we were unable to arrive at any method that would allow Haptek to run as nothing more than a trial version on my computer.
Haptek was basically set as a head modelling program only and still is! Some found you can capture and colorize the torso and fullbody characters but they cannot be changed to any extent. There is a program that I understand is quite expensive that can be used to create items, props, etc.
Only recently has someone figured a way to remove those awful boots from the full body character. Again, Haptek is a face only modelling program.
This site has LOTS of info regarding Haptek from usage to facial creation, etc. You just have to wade through the archives.
The site at
www.aidreams.com also has considerable info and examples of Haptek related material.
You can put your face on one of the Haptek faces but not really on the full body ones.
I'm certainly not the expert to ask but hopefully some of this info will help and others will weigh in on this thread.
Luck to you!
