Mirror Pro earns its place in the superhive library for tackling a quiet but common Blender annoyance, the flipped normals left behind after applying scale on mirrored objects, and folding the fix into the standard apply menu.
Mirror Pro (Fix Apply Scale Problem) is an installable Blender add-on from Cg Crafted that integrates into the Object/Apply menu alongside the default apply options. That menu is also reachable through Blender's CTRL + A shortcut.
It targets a specific issue: when you mirror an object it takes on negative scale values, and applying that scale causes Blender to flip the object's faces. Those flipped normals conflict with modifiers such as solidify and displacement, clash with texture normal maps, and can leave hair particles facing inside the object. The usual fix is to return to edit mode, flip the normals, then switch back to object mode.
The add-on applies scale while automatically correcting the normals, so mirroring or rescaling objects no longer flips their faces. It can apply scale and fix normals across multiple selected objects at once, right from object mode, and the developer notes that exporting to other programs stays problem-free.
Mirror Pro (Fix Apply Scale Problem) is best for blender modelers who mirror and rescale objects and need applying scale to keep normals correct.
Mirror Pro (Fix Apply Scale Problem) is completely free to download and use.
Mirror Pro (Fix Apply Scale Problem) lists compatibility with Blender 2.93, 3.0, 3.1, 3.2 and 3.3. The add-on installs into these versions and appears in the Object/Apply menu, which you can also open with the CTRL + A shortcut. If you run a newer Blender release, check the developer's page to confirm whether support has been extended, since the listed range covers those specific versions. Working within one of the supported versions is the safest way to get the expected behaviour.
Mirror Pro is distributed as a ZIP file. Download it, then open Blender and go to Edit, Preferences, Add-ons, Install. Locate the downloaded ZIP, install it, and enable the add-on. Once enabled, it appears in the Object/Apply menu among Blender's default apply options, which is also accessible through the CTRL + A combo. From there you can apply scale with corrected normals or fix flipped normals on selected objects directly from object mode.
Mirror Pro can apply scale and fix flipped normals across multiple selected objects at once, and it does this right from object mode. This matters because mirroring an object gives it negative scale values, and applying that scale flips its faces. Handling several objects together means you don't have to enter edit mode and flip normals one by one. The developer also notes that exporting these corrected objects to other programs stays problem-free.
Mirror Pro is listed as free in this catalog. The add-on ships under a Royalty Free license according to its listing. For the current terms and any licensing details, check the developer's page directly, since pricing and license conditions can change over time. Once installed, you get the apply-scale fix and the multi-object normal correction described here, integrated into Blender's standard Object/Apply menu.
