About SKkeeper

SKkeeper automates collapsing Blender modifiers without discarding shapekey data. It adds three operators to the 3D View’s Object menu: Apply All Modifiers (Keep Shapekeys), Apply Subdivision (Keep Shapekeys), and Apply Chosen Modifiers (Keep Shapekeys). Each operator is also reachable via the Quick Search (F3). The add-on works with Blender 4.2 LTS and newer and, as of version 1.8.2, can process multiple selected objects sequentially and operates on meshes with or without shapekeys. Certain modifiers that alter vertex counts unpredictably, such as Decimate or Weld, are not reliably supported and will trigger error messages indicating the problematic shapekey.

Features

• Apply All Modifiers (Keep Shapekeys): applies every modifier on the object while preserving shapekeys
• Apply Subdivision (Keep Shapekeys): applies only the topmost subdivision modifier and keeps the others
• Apply Chosen Modifiers (Keep Shapekeys): a popup lists all modifiers so you select which to apply
• Error messages that help locate a problematic shapekey when a modifier can’t be collapsed
• Operators reachable from the 3D View’s Object menu or the Quick Search floater (F3)
• Processes a selection of multiple objects, one after another (version 1.8.2)
• Works on meshes with or without shapekeys (version 1.8.2)

Best for

Blender users who need to apply modifiers on meshes that contain shapekeys or drivers without losing that data.
