How are vertex groups related to each other?
These vertex groups are sometimes also named ‘weight groups’ or ‘weight maps’. They are used for defining the weight tables of armature bones. All deform groups of an object are strictly related to each other via their weight values. Strictly speaking, the sum of all deform weights for any vertex of a mesh should be exactly 1.0.
How can I see the weights of the vertex group?
When you are in Edit Mode, you can make the weights of the active group visible on the mesh: Select the Viewport Overlays popover from the header of the 3D Viewport. And there enable the Vertex Group Weights option. Now you can see the weights of the active vertex group displayed on the mesh surface.
How do you find the weight of a vertex in Blender?
As mentioned before in Vertex Groups each entry in a Vertex Group also contains a weight value in the range of (0.0 to 1.0). Blender provides a Vertex Weights panel from where you can get (and edit) information about the weight values of each Vertex of a mesh. That is: to which Vertex Groups the vertex is assigned with which weight value.
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.
What happens when a vertex does not have weights?
If the active vertex does not have weights, or there is no active vertex selected at the moment, then the Vertex Weights Panel disappears. Each row in the Weight table contains four active elements: As soon as you select any of the Vertex Group Names in the Weight table, the referenced vertex group becomes the new active group.
How to mirror copy existing vertex weights in Blender?
Deselect all vertices by pressing the A key until the vertices aren’t highlighted. Under “Vertex Groups”, four new buttons have appeared. With “Group” selected, click “Select”. This will select the vertices in this group: Next, from the list of “Vertex Groups”, select “Group_copy”, and click Select.
How to remove weight from active vertex in Blender?
LMB the Paste button allows you to forward a single weight of the active vertex to all selected vertices. But note that weights are only pasted to vertices which already have a weight value in the affected vertex group. LMB the Delete button will instantly remove the weight from the active vertex.
Are there strict categories of vertex groups in Blender?
Actually we do not have any strict categories of vertex groups in Blender. Technically they all behave the same way. However, we can identify two implicit categories of vertex groups: These vertex groups are sometimes also named ‘weight groups’ or ‘weight maps’. They are used for defining the weight tables of armature bones.
How is the weight of an active vertex normalized?
Normalizes the weights of the active vertex. That is all weights of the active vertex are recalculated such that their relative weight is maintained and the weight sum is 1.0. Copies all weights defined for the active vertex to all selected vertices.
