attach them using NodeConstraints, then turn off FK/IK and that should work right? Although I guess the arms might do some weird movements.
Not sure about turning of the FK/IK after using Node Constraint, but yes that's correct.
Probably you might need to animate the upper body too since arm's FK/IK includes shoulder, elbow and hand.
The animations just seem super janky if you're using custom cards with differing proportions. Some animations I've seen random parts of the body flickering in and out, some I've seen the shadows of one of the charas hands moving all over the body when their hands aren't moving at all. Seems like a lot of manual work is required to get the animations to actually look good when using custom characters.
Flickering body parts especially shoulder and waist caused by abnormal position between hips (as the middle body bone) and waist (lower body) or the rotation of shoulder IK is weird.
For example, waist moves diagonally from XYZ 0,0,0 to 0,2,1 while hips linearly from 0,1,0 to 0,2,0.
In this case, the waist bone passed the hips bone in the middle of animation, which i think confuses the game hence resulting in flicker.
As for shoulder IK (also may happens on various bones), just try adjust the rotation in the HS2PE Adv., usually its caused by the base pose you chose to adjust.
For example, you chose a pose that female's arm is pulled from behind.
If you try to bring the arm to the front using IK, the shoulder will stay as if the arms is pulled whilst the lower arm is in the front of the body.
Of course this in unwanted, so you need to adjust it.
That's why you want to make the moving part is adjustable so when you replaced the chara, you dont have to remake the whole animation.
I always use IK Anchor and place them inside a folder.
The thing I register in the VNGE is the anchor, so when I replaced the chara to another with too much difference in height, I can just move the folder as an offset.
Well, animating stuff is indeed complicated and you only can embrace it
