>>2792732Go to the physics tab and enable physics first, brother.
Of note, this effect is caused by the way MikuMikuMoving treats After Physics bones, preserving their position at the last point physics were ON (or the original state) and only calculating them anew after you re-enable physics. For some reason, the author decided to use AP for hair and the chest itself. I follow the other approach: a movable base bone with an associated bone-tracking rigid, to which the rest of the physical chain is attached. Although having more rigids could be considered a very debatable disadvantage, it's also definitely an advantage if your model uses a modular approach, allowing to easily swap modules instead of having to readjust the joint connections every time or cluttering the model with duplicate rigids. Only use After Physics for cases like removable bikini, where you would otherwise have to create duplicate physics chains (copying the tit physics to the bikini cup in this case), and don't use them if your bone or a bone chain needn't follow existing physics.
>>2792734Wow, never thought GIMP would have an actual advantage over Clip Studio Paint, which has no way of accessing the alpha channel or faking it with layers, like you can do with a downloadable action set to separate the image into RGB channels.
