How can I see the weights of the vertex group?

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 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.

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.

What happens when you delete a vertex in Blender?

LMB the Delete button will instantly remove the weight from the active vertex. Thus the entire row disappears when you click on the delete icon. 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.

Is there a way to edit the vertex group?

This icon indicates that the vertex group can be edited. 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.

Where do I find the weight of a mesh in Blender?

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. The Vertex Weights panel can be found in the right Sidebar region of the 3D View.

How to assign a specific weight to vertices?

Ah, I was fooling around and found an answer. In ‘Edit Mode’ assign the desired vertex group and change their weight in ‘Vertex Groups’ panel. Enter the ‘Weight Paint Mode’ to see the result. Thanks for contributing an answer to Blender Stack Exchange!

Why do I need to rotate mesh for weight painting?

More often than not when I do weight-painting, weights on a model are the same/similar through the whole mesh (for example leg, arm), but weight painting has culling which prevents paint to go through the model and affects only visible part. To rotate around mesh for painting is often less precise and is always time consuming.

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.

How are the weights of meshes related in Blender?

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. In Blender this constraint is a bit relaxed (see below).

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.

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.
