28. Show FK Jnts
29. Select the FK end Jnt then Shoulder Ctrl Second Group ----- Constrain parent
-------------------------------------------------
Main Spline IK Setup
30. Hide all And Show Only Main Jnt
31. Go to IK spline Handel tool set Two Vertexes an Create From M_ Spain02_Jnt to Sholder Jnt (M_ Spain07End_Jnt)
32. Select the curve in the Center Of the Jnts Press Shift P to Un parent from the]
IK spline Handel .And Rename All .
33. Select the Vertexes of that Curve Create Clusters For each Vertex
34. The Select Top two Clusters Parent with the Shoulder Ctrl
35. The Select bottom two Clusters Parent with the Hip Ctrl
36. Then Create Two Null Groups By Pressing “Ctrl+G” Without Any Selection
37. Put the pivots At center Clusters (3rd Cluster) And Select Two Nulls then 3rd Cluster Constrain Parent.
38. Select null1 and Parent with Shoulder Ctrl ,Select null2 Parent with Hip Ctrl
COG Joint Creation
39. Create a Jnt at Root Start Jnt Name as COG
40. Hip Ctrl Pivot at M_ Spain02_Jnt and group it again Pivot at M_ Spain02_Jnt
41. COG Jnt to Hip Ctrl Parent and cog Jnt to M_ Spain01_Jnt Constrain Parent.
42. Root Ctrl to Hip Ctrl Constrain Parent .
43. IK Jnt to Hip Ctrl Normal Parent .
44. Select the 3rd Cluster and Parent With the Root Ctrl
1. Select the M_Spine_curve then go to MEL editor type “arclen – ch on;”
2. In M_Spine_curve chanel box we can find “Curve info” node select this node go to hyper Shade
3. Click on Input- output Connections
4. Drag out the “Curve info” node
5. Create 2 + 6 Multiply Divide nodes From Utilities and arrange like this
7. Select Curve info go to attribute Editor Copy “Arc length “ Value and past in Multiple Divider 02 –Input 2X .
8. Operation is Divide for Multiple Divider 01 and 02
9. Select all Main Spine Joints Except First Joint go to Hyper shade Graph Menu Add Selected To Graph and arrange
10.
11. Select Each jnt and copy Translate y value and past in the Multiple Divider –Input 2X in fornt of that jnt
12. Through connection Editor Connect the Curve info --Arc length to Multiple Divider 01 –Input 1X
13. Through connection Editor Connect the Multiple Divider 01 –output X
to Multiple Divider 02 –Input 1X
14. Through connection Editor Connect the Multiple Divider 02 –output X
To all Multiple Divider s –Input 1X
15. Through connection Editor Connect the all Multiple Divider s –output X
To all main spine jnts –translate Y
Then Check out The spine It Will Woks Same as PM Spline
