BVH2ARM is a script that ease the use of bvh with Blender by
automatically creating a parented armature upon a hierarchy of empties
.. as the one created by a BVH import .. The created armature follows the empties.
HOW TO INSTALL THE SCRIPT:
and place it into the ".blender\script\"
directory of your Blender Installation
HOW TO USE THIS SCRIPT:
First, you have to import a bvh content by using "File->Import->Motion
The first step
importing motion capture data.
To do so .. just use the menu File->Import->Motion
A file selector windows is displayed .. in which you can choose the bvh
file you want to import.
Once selected .. click on Import BVH.
You should be asked to enter a scale parameter which allow you to size
the resulting structure.
Once the scale is selected .. press OK
script will then build a hierarchically structured heap of empty such
as the one shown beside.
The newly created structure should be facing the sky .. and lying on
To see it properly ... switch to a top view (NumPad 7)
and zoom out (- minus key)
You can press Alt-A to play the bvh animation.
following steps, the first frame of the bvh animation will be
used as the rest position of our armature.
In order to have it suit our model, it might be interesting to adapt
this rest position at our model position .. (which might have arms set
in horizontal position instead of lying along the torso)
At frame one, select a shoulder empty (RMB-click on it
and rotate it 90 degrees (R key, mouse move, while
Ctrl key pressed).
Do the same with other shoulder empty to get something similar to
what's shown beside .
Now select both shoulder empties (RMB-click on
holding Shift-key pressed) .. and insert a
Rot Key (press I and select Rot
in the displayed
This cannot be applied to Hips empty .. We'll see later how to rotate the resulting armature.
HipBoneName field must be filled with the name of the main empty of the
structure. It is automatically set to the name of the selected empty if
it is a root Empty (ie: if it has no parent).
The startframe and endframe
fields can be
used to configure the It is recommanded to use the frame
as the first frame because it's going to be the rest position of our
armature. By default, these fields are set to your animation parameter
(defined in the anim tabspace of the scene panel (F10))
The FrameDecimation field allows to select
at which position key are going to be inserted into the armature
Once all parameters are set ... Press Create Armature
It creates an armature which follow the empties ..
Go into Ipo of Armature, select rotX curve and grab it 9 unit up..
