Why we like it

Corrective Smooth Baker earns its place in the superhive library by targeting a specific gap: the Smooth Corrective modifier's effect is confined to Blender and lost on export, and this add-on bakes it into vertex weights so it carries through. Note that Mesh Online has folded the same functionality into its Voxel Heat Diffuse Skinning add-on.

What is Corrective Smooth Baker?

Blender's Smooth Corrective modifier, a form of Delta Mush, reduces highly distorted areas of a mesh by smoothing armature deformations, but it only works inside Blender. Export an armature-deformed character to a game engine and the smoothing is lost. Corrective Smooth Baker from Mesh Online addresses this by baking the Smooth Corrective modifier into vertex weights, so the smooth effect stays with the exported character.

To do it, the add-on twists the armature to generate a large number of dynamic random poses and derives vertex weights from them, so the result fits any pose. You can watch the baking happen in realtime through a progress bar that reports the completed percentage, the completed and total vertex counts, and the remaining time.

In Blender 2.80 and later, the interface appears in the View3D sidebar under the Mesh Online tab once you select both the mesh object and the armature. Tutorials cover the basis workflow along with Auto-Rig Pro and Rigify setups. Mesh Online has also integrated this add-on into its Voxel Heat Diffuse Skinning add-on.

Who is Corrective Smooth Baker best for?

Corrective Smooth Baker is best for blender riggers who need armature-deformed characters to keep their Smooth Corrective smoothing after exporting to game engines.

How much does Corrective Smooth Baker cost?

Corrective Smooth Baker is completely free to download and use.

Frequently asked questions

Does Corrective Smooth Baker work with Blender 2.80 and newer?

Corrective Smooth Baker exposes its interface in Blender 2.80 and later, appearing in the View3D sidebar under the Mesh Online tab once both a mesh object and its armature are selected. Its listed updates also mention performance improvements for Blender 2.93 and 3.0, plus fixes for Blender 2.93 Alpha, so it has been maintained across several releases. For the exact range of supported Blender versions, check the developer's page before installing.

How do I install Corrective Smooth Baker in Blender?

Corrective Smooth Baker installs from the downloaded zip file. In current Blender, open Edit then Preferences and Get Extensions, expand the Repositories dropdown, click Install from Disk and select the zip. The legacy route uses Edit then Preferences and Add-ons with the Install Add-on from file button, after which you activate the add-on and save your user settings. To upgrade, uninstall the current version first, then install the new one from disk.

Will the smoothing survive when I export a character to a game engine?

Corrective Smooth Baker exists for exactly this problem. Blender's Smooth Corrective modifier smooths armature deformations only within Blender, so the effect disappears on export. By baking that modifier into vertex weights, the add-on preserves the smoothing on the exported character. It generates those weights from a large number of dynamic random poses, created by twisting the armature, so the baked result fits any pose rather than only a single frame.

Is Corrective Smooth Baker free?

Corrective Smooth Baker is listed as free in this catalog. Licensing terms can change, so check the developer's page for the current details. It is also worth knowing that Mesh Online has integrated this add-on into its Voxel Heat Diffuse Skinning add-on, so if you already own that one, this functionality is included there. You can still install Corrective Smooth Baker on its own if you don't need the voxel skinning tools.
