VMath integrates mathematical operations directly into Blender's vertex groups panel, providing precise control over weight distributions. The tool allows users to combine, subtract, multiply, and divide the weights of different vertex groups. It also includes functions for union, intersect, and invert operations to isolate or reverse specific areas of influence.

For advanced control, the tool supports batch editing to apply operations across multiple unlocked groups simultaneously. It also respects vertex masking, enabling users to restrict calculations to specific vertex selections while working in Weight Paint mode.
