Quote - Does anyone know of a tutorial for editing poser fct files?

the main issue is that it always comes up saying that this is not for this figure
it is v4 and the file was made with v4?....duh...

Maybe you mean fc2?  I don't know fct

With face file you get message similar if you have not injected morph that file is looking for.
It can't set value for morph not there, so it say not for this figure
