I read through what is intended in 2020 and I am not that excited.
     When I buy, or download, an upgrade to a program I expect it to do what the previous version did, only better and faster. Money is changing hands here, so one would presume this is logical. Reallusion seem to think the opposite. They take my money and then take away functions, and in the upgrade I don’t remember being told that such-and-such is now removed. Why should I now ever bother upgrading if it seems my older versions are better?
     I refer to the inability of a CC3 base to accept a decal. I can do it with a CC1 base and convert it - brilliant, but what if I am creating with Headshot which can only be applied to CC3? I can find no way to retro-convert, and if there is; why? Why do I need to go backwards?
     My character, based on a friend, has tattoos. I can add them to the face photo, even the diffuse photo, but the past ease and simplicity of adding them to the torso, arms etc, has now gone, and seemingly impossible to do, unless I use Crazy Talk and CC2, thereby rendering the purchase of Headshot as a waste of money. Tattoos are extremely normal in reality, and fantasy, so it seems ridiculous that they have become so difficult, if not impossible, to apply to a character. 
     I really hope that I am over-looking a simple answer to adding decals to a CC3 character, but another bugbear, the frustrating difficulty of searching the Forum for answers, gets in the way. No doubt this issue may be addressed in the future, but will I be bothered buying it? No, luckily I’ve still got CC2, and, because it seems aspects of CC3 are redundant, I have no need for anything else as CC2 answers my immediate, and I presume future, needs.
