Chris_solo Unfortunately, Spine does not offer many convenient features for creating symmetrical rigs. Therefore, if you want to achieve complete symmetry, you will need to put some thought into it.
First, regarding how to set bones symmetrically, the general approach is to flip the created bones using negative scaling to achieve symmetry. However, this results in the duplicated bones always having a negative scale, which may be concerning. In such cases, the method demonstrated by Erika in the following video—first flipping the bones using negative scale, then copying the transform and pasting it—is the cleanest way to achieve symmetrical bones:
The video above was published before the convenient Weld feature was added, so the weight is adjusted manually, but now you can follow these steps:
- After setting the weights for the vertices on one side of the mesh, duplicate the mesh attachment.
- Flip the duplicated mesh attachment by setting the Scale X or Y to a negative value.
- Select the original mesh and select the vertices for which you want to set the weights.
- Select Weld->All in the Weights view and select the duplicated mesh attachment.
If the number of vertices is not that large, it may be quicker to simply copy and paste the weights rather than following the step above, but for complex meshes, using Weld will be useful.
I hope this answer helps you.
