Vmath : Vertex Group Weights

by Inlet in Addons



VMath was developed to meet the demand for enhanced precision and control over vertex groups, empowering you to manipulate them in unprecedented ways. Think of it as a powerful calculator for your vertex groups! Here’s a breakdown of the operations available:


  • Add merges two vertex groups by summing the weights of each vertex, allowing for stacked influences.
  • Subtract removes the weights of one vertex group from another, giving you finer control over vertex influence compared to Blender’s default option of merely setting values to zero.
  • Multiply and Divide adjust the weights of the vertices, reducing influence in regions where either or both groups have minimal weight, while preserving the existing weight elsewhere.
  • Union captures the highest weight value from two vertex groups for each vertex, enabling you to combine groups while retaining the strongest influence from both.
  • Intersect identifies the minimum weight, pinpointing the areas of shared influence and isolating the regions affected by both groups.
  • Invert reverses the weights within a vertex group, transforming high values to low and vice versa, which allows for a quick negation of a group’s effect.








VMath Pro offers advanced features like Batch Editing and Vertex Masking:

Batch Editing allows you to apply an operation to all vertex groups simultaneously with a single click, bypassing any locked groups.

Vertex Masking enables you to manipulate only the selected portion of the mesh instead of the entire model. This feature is activated by choosing your desired vertices in Edit Mode and turning on the ‘paint mask’ in Weight Paint Mode.

With VMath, you gain more than fundamental control; it’s your new resource for precision, efficiency, and creative freedom in managing vertex groups within Blender.
