Fader Addon earns its place in the superhive library as a focused utility for one job: transparency control across single or multiple objects, refined over several releases to handle objects with multiple materials.
Fader Addon works by assigning transparency to objects in Blender so you can look inside a model, edit hidden parts, or produce renderings with gradients of visibility. Select an object, press the Object Fader button, and adjust the Fader Strength slider to control how transparent it becomes. If the object has no material, one is assigned; if it already has a material, the button applies 50% transparency while keeping that material.
The Multi Object Fader button applies the same effect to several selected objects at once, giving all mesh objects 50% transparency. Moving the Fader Strength slider changes only the active object, so each object can hold a different strength, and pressing the button again resets selected objects to the default. The Name Active Object checkbox displays an object's name, which helps when the slider is at zero and the object is no longer visible.
Solid mode and material preview mode give the same result, and the Change Fader Color button assigns a color visible in solid mode without affecting the material. The Fade All Materials checkbox fades every material assigned to an object at once.
Fader Addon is best for blender users who need to see or edit parts hidden inside a model, or render objects with varying levels of visibility.
Fader Addon is completely free to download and use.
Fader Addon lists compatibility with Blender versions 3.0 through 5.0 and is marked as Blender Extension compatible. Its development history reflects this range, with updates released for Blender 4.0 and Blender 4.3 along the way. If you run a version within that span, the add-on's transparency controls, sliders, and buttons are intended to work as described. For the current compatibility status on your exact Blender build, check the developer's page before installing.
Fader Addon is listed as working with the Blender-Internal, Cycles, and Eevee render engines. The transparency effect also behaves consistently between solid mode and material preview mode, so the result you see matches across both viewport shading options. When you switch to solid mode, the Change Fader Color button lets you assign a color to an object without altering its material. This makes the add-on usable whether you are inspecting geometry in the viewport or preparing a render.
Fader Addon is listed as free in this catalog, so you can add it to your Blender setup without a purchase here. Licensing terms can change over time, and the add-on is distributed under the GPL license. For the current pricing, licensing details, and any updates from the developer, visit the developer's page. Checking there also confirms the latest release and version notes before you download the add-on.
Fader Addon added support for objects with multiple materials in a later update. The Fade All Materials checkbox fades every material assigned to an object at once, while leaving the checkbox unchecked keeps the earlier behaviour of fading only the active material. This gives you a choice between fading a single material or all of them together, for both single objects and multiple selected objects. The option applies whether you use the Object Fader or the Multi Object Fader.
Fader Addon handles this through the Multi Object Fader button, which applies 50% transparency to all selected mesh objects at once. Moving the Fader Strength slider then changes only the active object, so you can set a different strength for each one in turn. Pressing the Multi Object Fader button again on objects that already have a strength resets them to the default. The Name Active Object checkbox displays an object's name, which helps track it when the slider is set to zero.
