Particle Pie Menu, developed by VFX Grace, is a Blender add-on focused on editing hair particle systems through pie menus. It organizes options by mode so tools are reachable while you work. In Object Mode you can change the hair display color, modify the order of particle systems and their settings, adjust particle render options such as strand shape, render and display steps, and material assignment, and switch children types between None, Simple, and Interpolated.
In Edit Mode you can pick a particle brush from the pie menu with one click, along with particle editing options including displaying children, setting path steps, enabling symmetry on the X axis, preserving strand lengths, and preserving root position. Additional functions include toggling X-ray, setting random hair colors, keyframing the particle system display, moving the modifier to the top or bottom, and resetting or transferring hair weight to a selected item.
Reset Hair Weight and Copy Hair Weight to Selected Item both open a confirmation dialog before running. The weight transfer uses the generic data transfer, moving from the selected object to the active one, and suits transferring weights between an object and its copy.
