Applying Groove Bone [Sadistic Love] by AddestorionVayanis Applying Groove Bone [Sadistic Love] by AddestorionVayanis
Pretty sure there are many others around

I found a lovely Sadistic Love motion data by あひる@anatroccolo… but i found out that most of models behaved weird. So this is a personal reminder of what to do when i encounter a groove bone related problem.

Groove bone - グルーブ
Note: depending on the motion, it has to be EXACTLY that text. the google translate version gives グルーヴ, but its not the same, so it will not work. Different models have slightly different spelling, so you have to find the exact spelling in the .vmd file

But now it works for me.

Testing was done on a Ula Kagamine Rin White2 type, although i edited most of the models i have to be compatible with it.

Testing on MMDAgent.…
Skip to 6:07 , the one on the left is unedited, the one on the right is the edited groove bone model.

This isn't working for any of my models that don't have groove bones. I have no idea what I'm doing wrong. ;n;

do they have a master bone?

if they do, you will need to connect it so that it becomes
Master >> center >> groove

in this case, just add a connecting bone from the master bone, and rename it center, while your rename your center bone as the groove bone

Okey... I'm so confused...

Could you help me make this:… Motion data work? Please?

you do need to specify which model that youre using so that i can check if the model has anything unusual that may affect the groove bone position.

Well... I am using the Young Adult Dancer Len Kagamine, and the Aratana Len Model.

Those two are mainly the models I use. :)

the original model, the Akatonbo Rin Kagamine model was compared to the Aratana Len model.
There are a few differences, in that the groove bone is after the center bone, and not before.  This differs from the steps above.  But i have identified how to make it work.

The model needs the following, in this order

Parent master bone (0,0,0)
Center (0,8,0)
Groove (0,7,0) - previous center bone

Use the 'add master bone' function to start off.
Rightclick the add master bone, and add a connect bone (Ctrl+L)
change its name to a center bone (change the coordinates to 0,8,0)
change the old center bone to groove bone
change the coordinates to 0,7,0

ensure that all the bones are connected in that order.

what's a groove bone? :)
AddestorionVayanis Featured By Owner Oct 26, 2013
its an additional bone, usually added before or after the center bone.  Some new motions make use of it, so if your model doesnt have a groove bone, your motion is going to come out weird.
