How can I automatically generate vertex groups for an armature?
Try using Ctrl P and select automatic weights, to parent the mesh to the armatures to automatically create the vertex groups. A new method to create vertex weights for bone deformation was added, next to the existing method based on envelopes.
How to assign vertex groups to bones precisely?
Vertex groups are selected in the armature options, the vertex group names correspond to the bones I want them to be attached to, and I parented the armature to the mesh with the ‘armature deform’ option (I tried automatic weights and the result was even worse).
Is there a way to remove vertex assignments?
You can add vertex assignments to the group or remove assignments from the group. And you can change it with the weight paint brushes, etc. When you click on the icon, it changes to a closed padlock icon and all vertex group modifications get disabled. You can only rename or delete the group, and unlock it again.
What happens when a vertex group is locked?
When you click on the icon, it changes to a closed padlock icon and all vertex group modifications get disabled. You can only rename or delete the group, and unlock it again. No other operations are allowed on locked vertex groups, thus all corresponding buttons become disabled for locked vertex groups.
How to parent the mesh to the armature?
Additionally, you can also parent the mesh to the armature as empty groups.. and then select the bone while in Pose Mode, open the Specials menu with W or from the weight paint view header and choose Assign Automatic from Bones, this can give you a bit more control over how your groups are created as you can see it on the fly and edit it further.
When to use bone heat for vertex weights?
A new method to create vertex weights for bone deformation was added, next to the existing method based on envelopes. The new bone heat method often generates better results, and does not require setting a radius for bones. It can be used when parenting a mesh to an armature by selecting “Create From Bone Heat” from the available options.
