can you explain a bit how it will be faked because I am using studio animations and haven't learned to create custom animations
As Kaseijin explained, all you can do is be creative and utilize what you have in the studio.
For example, both characters are facing each other and the chara1 is groping chara2 breasts.
You understand that the breast themselves shouldn't have jiggle too much (since they're held by the hands).
So what you can do in this situation? Make the hand as if holding the breast and decrease the breast jiggle.
But how do you do that?
Usually I will do these :
- Constraint : chest -> hand IK. So the hands will follow the chest position
- Constraint : palm -> breast. So the breast shape will be locked to palm
- Add movement to the hand either move them yourself, add physics to follow the female body's movement, or both. Depend on my mood
Those are just the basic. Even though there are only two constraints here. It doesn't mean there would be only 2 entries. Might be 4 entries just for the step 1 and 2 for each breast side. So it make 8 entries for both side. And the step 3 will add few more entries.
Yes it's tiresome, so its not wrong to chose not to make breast groping animation. Even I won't make it deliberately. But some this principle can be applied to various pose such as boobjob.
