The tail of the Lamia model does not move by default.

The reason is that it is calculated in MMD as a physical bone.

So I changed the physics bones to normal bones.

【How to change physical bones to normal bones】

①Change physics calculation settings

There are several types of physics calculation methods in MMD.

I used two types of physics calculations.

?On/Off mode (cannot see the physics bones)

?Trace mode (can see the physics bones)

You can change these settings freely by clicking on "Physics Calculation (P)" in the menu tab.

②Open fish tail bone tab

Lamia fish tail bone included in “その他:etc”tab→”TailBone” tab.

③Change × to ◆.

First, select all TailBone. All the tabs you selected will turn red. Then look at the blue square menu at the down side of the screen.

In the blue menu called "Bone Control", there is a button called "物理:Physics". After clicking this button, click the button "登録:Registration".

Next,

Look at the TailBone tab you selected.

Has it changed from × to ◆? If ◆ is displayed, you have succeeded.

?×→ physical bourne(cannot be moved)

?◆→ normal bourne(can be moved)
