and this are
Open the poseDeformer window, select your skin in the first field.
In the second field, right click and choose 'create new poseDeformer', which will create poseDeformer2.
Right click again and select poseDeformer1
Click the 'mirror' button
Right click in the 'deformer to' field, choose poseDeformer2
Set the correct mirror axis
Enter the correct search and replace fields, eg, replace L_ with R_, or Left with Right, or whatever left/right prefix/suffix you use.
Hit mirror, wait while it does its thang
When done, delete the mirrorData node if its been left behind
i follow all the steps, but i don`t know where to find the mirrorData node, perhaps that is what turns everything slow...
any help is welcome and appreciate
