Bone Tools Mirror

It doesn't make sense to rig all the bones of a bilaterally symmetrical character—that's a waste of time. What you really want is to rig just one side and have the software mirror the bones to create the other side. 3ds max 7 now adds this ability with Bone Tools Mirror (Bone Tools > Bone Editing Tools > Mirror). This is accessed with a new Mirror button added to the Bone Tools dialog. You select the bones to be mirrored; the mirrored bones will be named similarly to their original bones, but with the word “mirrored” added in parentheses (Figure 4.18).

Figure 4.18. The new Mirror button, located in the Bone Tools modifier, opens a dialog to select the axis. The new bones are named according to the original, with the word “mirrored” in parenthesis.


The old method was to use the Mirror tool from the toolbar, which caused the Scale value of the mirrored bones to be flipped to a negative 100 percent on the mirrored axis. Bones that have their scale flipped to a negative do not rotate consistently on their local axes. The new Mirror tool in the Bone Tools dialog keeps the mirrored bones at plus 100 percent, where they belong.

Tip

The mirrored bones are not Instances, so you should only mirror the selected bones when all adjustments have been made to one side of the rig.
