Turn existing surfaces into animated stone

Apply a shared surface effect to selected meshes or the editable meshes of a rig. Keep original materials ahead of the transition, choose radial expansion or a directional sweep, and use Petrify/Reverse to insert progress endpoint keys.

Your download

Directly installable product ZIP, 6-page English and Spanish PDF manuals, matching Markdown guides, full source license and an original procedural sentinel Blender demo. Install the product ZIP directly in Blender. Extract a copy to read the manuals.

Requirements and scope

Windows tested: Blender 4.2.0, 4.5.2 LTS and 5.2.2 LTS; Eevee/Cycles workflows. macOS and Linux have not been tested. Use Object Mode and editable local meshes. Test complex custom shaders in your own render engine.

Surface material effect only: no actual mesh fracture, debris, automatic rig freeze or conversion of hair cards into solid hair. Active Geometry Nodes are rejected; apply/convert on a duplicate first. Stable-topology deformation is the intended scope. Animation buttons add two keys and preserve other existing keys, which may affect the curve. The showcase pause is separate NLA scene preparation.

The walking character and animation in the videos are not included. The download includes the original procedural sentinel instead. Addon source: GPL-3.0-or-later.
