About Apply modifier with shape keys

Blender normally prevents applying modifiers to a mesh that has shape keys, showing the error “Modifier cannot be applied to a mesh with shape keys.” This add‑on works around that limitation. It duplicates the original mesh, removes shape keys, applies the chosen modifiers, then processes each shape key individually: it evaluates the mesh with that shape key and the active modifiers, merges the result back as a shape key, and finally restores all original shape key values, animation data, and driver settings. The workflow reduces memory usage on high‑density meshes by handling one shape key at a time. The tool is accessible for Mesh objects in Object Mode via the Shape Key context menu or the F3 search, and presents a popup with checkboxes to select which modifiers to apply.

Features

• Applies selected modifiers to meshes that already carry shape keys
• Restores shape key values, animation data, and drivers after processing
• Processes shape keys one at a time to reduce memory load on high-density meshes
• Popup dialog with checkboxes for choosing which modifiers to apply
• Available for Mesh objects in Object Mode, from the Shape Key context menu or F3 search
• Avoids the apply-modifier operator when applying modifiers and merging meshes

Best for

Blender artists who need to apply modifiers to meshes that already have shape keys while preserving associated animation data and drivers.
