Finalizing the project.
17. In the Project Workspace, select the “Everything2” bone. Drag it on top of the “Everything” bone. Delete the “Eveything2” bone. Save the file.
18. Go into the “Rig” Pose. Making sure that the “Key Constraints” and “Key Model” buttons are depressed at the bottom of the screen, drag “Rig2” onto the Pose screen. That will apply all the data from that Pose into the current one. Do this with “Rig3” as well. You’ll know this has been done correctly when the 2 other legs snap into place. Once finished, delete the “Rig2” and “Rig3” Poses, and save the model.
Dragging the “Rig2” Pose onto the “Rig” Pose. Make sure that the “Key Constraints” and the “Key Model” buttons are depressed.
19. Now we have a fully functioning right side!
20. I recommend adding two more bones for the purposes of making animation and organization easier. In bones mode, add the first bone at the center of the model space. My values for this bone are
| Start Pos. | End Pos. |
|---|---|
| 0 | 0 |
| 18.82 | 18.82 |
| -10 | 40 |
Call it “Thorax”
21 .Add another bone somewhere to the right (that is, the right of the model’s – if you’re in Top View, you will draw it on the left side of the model from your perspective) of the center bone. Call it “R_Side”.
Having added the “Thorax” and the “R_Side” bones.
22 . “R_Side” should be a child of “Thorax”, and you should now drag “Thorax” on top of “Everything”. Then, drag all the limbs onto “R_Side”. The feet, however, should remain children of “Everything”. Hide the “Everything” bone and the “R_Side” bone.
The final hierarchy of all the bones. By putting the Feet bones at the same height as the Thorax, when you move the Thorax around, the feet will stay planted in place.
23. Open a new Action, apply the Rig Pose and have fun! : )
Don’t believe me? Watch a Quicktime movie of a walk cycle that I very rapidly produced with the rig and see for yourself!
