A quick tutorial for how to setup IK arms for models for mikumikudance!

NOTE: This is mostly useful just for custom animating, if you wanna make arm movements quick and dirty.

NOTE2: The IK arms setup here isn't perfect, the arms can bend the wrong way, clip inside the body and so on. Like just mentioned above, this quick and dirty.

Aaand again, kinda to condense what to do:
1. Find a wrist bone in the "Bone" tab of PmxEditor and make a new bone one number above the wrist bone, just right click on the wrist bone on the list and hit "Add > Add here" to do this.

2. Set the new bone as IK and also enable MVN, set it's position to where the original wrist bone is located.

3. Set the parent bone (P-Bone) to whatever works for you (I recommend the upper body)

4. Set IK target to the wrist, set Loop to 40

5. Copypaste the elbow bone's value/index into the "Link" box, then the shoulder.

6. If there's any twist bones for the arms, delete those. I'm not sure if this is the case, but I feeeeel like there's a chance the arms might break while deleting those bones. Try first deleting any visible twist bones, then any invisible ones, starting from the ones closest to hands. Again, I'm not sure if doing it this way matters, buuuut it has worked for me when editing some Persona 3 and 5 models.

7. Forgot this one from the image, but yeah it's pretty important for animating: ADD THE NEW BONES INTO DISPLAY PANEL, copy the indexes of the new bones (Right click, Copy Index), then go to the Display tab and add them into one of the groups, IK group probably makes the most sense. If you won't do this you'll have a difficult time handling and finetuning your animation.

It might seem like much but honestly, it goes pretty fast once you know what to do, create bones, set positions, add elbows and shoulders. I had to figure this stuff out because a plugin called IKMakerX, made for creating arm IK's, juuust didn't work for me no matter what versions of the plugin or PMXE I tried using.
