Hello.
While I enjoy my cards very much and I know some of you do too, I also know you have your own favorites. This is why I always do my best to create my scenes in a way where switching cards is easy.
Depending on body proportions, some animations might normally break. However, I think I have found a way around it. If you open any of my animation, you will see I make heavy use of folders to animate things. There are multiples reasons as to why, but one of them is related to that issue.
Some of these folders are called "adjust". As their name may suggest, these folders can be used to adjust the position of bodyparts. Say, for instance, that your character is taller than the one used in the animation. You can move the "adjust" folders out and away to potentially fix the animation.
I can't promise this will work every single time, but it usually does the trick. Hopefully this little trick helps you enjoy my work even more.
