What are you guys on about? The character mesh probably uses morphs to conform to whatever you make. How else did you expect the program to make characters on the fly?
Complaining about the trial version saying that you would probably have to pay $200 to make it work is insane. How much do you think it costs to scan and make a photo realistic character from scratch? Trust me. Way more then $200 just in time and effort then you think.
And instead of coming on to the unreal answerhub for answers about a product that isn’t made or managed by Epic, have you tried the character maker support channels at all? What do they say?
