Plumbob replacement mod problem. help?

I can't help with changing which part of the body the plumbob is assigned to but I might have a rough idea about the spinning.
I believe that the spinning is controlled by the shader that the plumbob uses.
I've not looked at how the plumbob is setup before but assuming it is basically setup the same as any other object then here's how to change that.
Go to the Model LOD entries in the Warehouse tab. You're looking for the ones that have a chequered black and white pattern on them in the 3D view. The solid grey ones are shadow meshes and should be left alone.
Switch to the Data tab above the 3D view.
Click on Edit Items...
In the new window click on the shader for the plumbob in the list on the left.
Scroll down on the right until you find the Material section and then click Edit Items... next to Entries.
I'm guessing there might only be one entry in here. Regular objects have multiple entries because of object recolours and different object states such as being burnt. If there are multiple entries you'll probably have to make the same edits for them all.
Click the Edit Items... button on the right. You're now in the location needed to change the shader settings.
I don't know the setting's specific name but you will be looking for something in the list on the left relating to rotation speed or direction.
Change the settings to 0 and that should disable any spinning.
Keep pressing save until you get back to the main Studio window again.
You may also need to do this for the Model resource as well.
Click on Edit Items... next to Lods.
Select the lowest detail entry on the left that isn't a shadow.
Click Edit Items... next to Meshes and continue as before.

I hope you can follow all that and that I'm actually correct in assuming the plumbob works similarly to all other game objects.

gabeflxtcher The triangle only appears when you're on the mesh!
So click the mesh instead of the rig and then it'll pop up :D

I'd suggest:

1.Re grabbing the file with the original plumb bob
2.put your new plumbbob in
3. click the original plumb bob then highlight your selection,
3.a in the bottom left of blender click the drop down box (it probably says object mode) choose weight paint
3.b. on the left select transfer weights
4. then re replace the plumb bob as you did before

OH hang on.
Half way through writing I just realised this isn't the thing you need
(Just incase it's useful though I'll leave it in :D)

>After Adding the Root Bone, Did you click Assign?<

1.in the bottom left of blender click the drop down box (it probably says object mode) choose weight paint and paint the weights on the new plumbbob

(You can also test to see if it works on a different bone if the root bone doesn't want to play ball!)
Here's a link to grab the other bones!

Try adding it to her foot possibly just to check it moves!

Hopefully that'll do it!

It would have been the same way, yeah. I guess that just means that the Phong shader can't make use of those settings.

As for your import issue, studio won't let you add or change bones that aren't in the mesh when you export it. I've had it before with regular object making when I've combined objects. The only way to get the mesh back in for me was to remove the bone mentioned in the error message.
I don't know if you can add the bone to the package BEFORE you export the mesh to blender for editing.

I think I'm at a loss now to be able to provide anymore help or suggestions.

Ty!
