Sits in the superhive catalog as a focused scan-cleanup tool: geometry decimation, floor and axis trimming, texture patching, and instancing gathered into one Blender panel.
Cleaning 3D scans frees up computer resources, saving more than 80% of memory in some cases, but done by hand it eats time, averaging around five minutes per scan across a large collection. 3D Scan Cleaner, an add-on for Blender by Ignacio Matey, reduces that to a couple of clicks.
The Clean Geometry menu drives the work. Decimate Ratio controls how far the mesh is simplified, Floor Height removes vertical geometry to strip out the ground that scans usually carry, and X/Y Cut does the same along the X and Y axes. Apply decimates the mesh, deletes the floor and XY sides, and removes extra mesh islands, while Reset clears the modifiers. Applying is destructive, so you re-import the object to recover the original geometry.
Fix Texture opens the Texture Paint viewer with the Cloner tool to patch stretched or missing texture spots, and Instance Geometry lets you reuse a cleaned scan without duplicating data or risking crashes, with an option to randomize instances. It requires Blender 3.1 or higher.
3D Scan Cleaner is best for blender artists cleaning and optimizing large collections of 3D scans.
3D Scan Cleaner is completely free to download and use.
3D Scan Cleaner requires Blender 3.1 or higher, and it will not run on older releases. If you are on an earlier version, the add-on won't work until you upgrade to a supported build. Once you are on a compatible version, you install it through the Add-Ons preferences and open its panel from the N-key sidebar in the 3D viewport. From there you can reach the geometry cleaning, texture fixing, and instancing tools that the add-on provides.
3D Scan Cleaner installs like a standard Blender add-on. Download the provided ZIP file, then open Blender and go to Edit, Preferences, Add-Ons, and choose Install, pointing it at the ZIP you downloaded. Activate it by searching the Add-On menu for 3D Scan and enabling it. Once active, press N in the 3D viewport to reveal the panel on the right, where the cleaning, texture, and instancing controls live. Keep in mind it only works with Blender 3.1 or higher.
3D Scan Cleaner includes a Fix Texture tool for spots where the texture is stretched or missing, which is common in areas that got less attention during scanning. It opens the Texture Paint viewer with the Cloner tool selected. You place the 3D cursor over a spot where the texture looks nice and detailed, then paint over the flawed area, and the texture next to the cursor is copied across. Remember to save the image once you are finished, and avoid render view during this step.
3D Scan Cleaner offers an Instance Geometry option for reusing a scan within your scene. Copying, pasting, or duplicating a scan generates more data and can occasionally crash Blender, whereas instancing adds it without that data cost. The add-on also lets you randomize the instance so repeated copies don't look identical. This is meant to be used after you have finished cleaning the geometry and, if needed, fixing the textures on the original scan.
3D Scan Cleaner is listed as free in this catalog. For current licensing terms and any conditions attached to the add-on, check the developer's page, since offers and terms can change over time. Historically the developer bundled six optimized historical 3D scans captured in Creta, Greece, at no extra charge as part of a launch promotion, though that offer was tied to a specific date and may no longer apply. The developer's page is the best place to confirm what is currently included.
