Vertex Paint Mode
Mirror the brush strokes across the selected local axes. Note that if you want to alter the directions the axes point in, you must rotate the model in Edit Mode and not in Object Mode.
- Radial X, Y, Z
These settings allow for radial symmetry in the desired axes. The number determines how many times the stroke will be repeated within 360 degrees around the central axes.
- Vertex Groups X Symmetry
Mirror the left/right vertex groups when painting.
