Set Driven Keys.

1. Open up set driven key.  Load l_arm_ctrl into driver and select 'Close'  Load l_finger1_joint into driven and select 'Rotate z (y on ladybug)' Make sure everything is zeroed out for the first key.  Press Key. 

2. Change driver value 'close' to 10. Make sure you always change the driver first.  Change driven value 'rotate z' to -120 (about) Press Key. 

3. Open set driven key again.  Load l_arm_ctrl into driver and select 'thumb'  Load l_thumb1_joint into driven and select 'rotate x,y,z'  Have all zeroed out.  Press Key. 

4. Change thumb joint to '10' and put thumb where needed to get the rotae x,y and z values. Press Key. 

^^^ Do the same for the right side. 

Edit attribute: - Tick the boxes that allow the attribute to have minimum and maximum values. Put min at 0 and max at 10. 

Open outliner and select the fingers and thumbs and make sure all tangents are linear (straight). It is now up to the animator to put in the timing. 

-------------------------------------------------------

Next steps in assignment: 

- Make a control group and a don't touch group.  - Select all under global_ctrl and group again. Name this group global_buffer. Then unparent global_buffer and global_ctrl from one another. Select global_ctrl THEN global_buffer and parent constrain and scale constrain.  - Lock off all attributes that do not need to be used. 

----------------------------------------------------------

To Bind: Under 'skin' go: 'smooth bind options' 

Make sure to have selected.  - joint hierarchy - heat map - classic linear  - post

make sure to turn off colorize skeleton too.
