Why we like it

Alpha Setter stands out in the Superhive library as a focused, single-purpose add-on: it keeps vertex alpha visualization, inspection, and editing in one N-Panel tab and adds Blender 5.0 support.

What is Alpha Setter?

Alpha Setter is a Blender add-on focused on vertex alpha. It shows real-time vertex alpha visualization in the viewport and works across Object, Edit, and Vertex Paint modes, so you can preview and inspect exact alpha values per vertex as you work.

In Edit Mode, you can edit alpha values directly and apply a one-click Brightness/Contrast adjustment for vertex alpha. Access is through the N-Panel Alpha Setter tab in Object Mode or Edit Mode, where you visualize, inspect, and edit. The add-on is compatible with both Vulkan and OpenGL backends and uses the Cycles and Eevee render engines.

Installation is done by dragging the .zip into the Blender window, or manually through Edit → Preferences → Add-ons → Install, then activating the add-on. It is suitable for environment and props artists needing precise and visualized control of vertex alpha.
