Sculpt Pose Sync earns its place for tackling a specific pain point: symmetrical sculpting on a posed model without losing sight of how the pose deforms the mesh, handled through an automated dual-mesh workflow rather than manual setup.
Sculpting symmetrically on a rigged, posed character in Blender normally means resetting the armature to a rest pose such as T-Pose or A-Pose. That hides how muscles or clothes deform in the final pose. Sculpt Pose Sync, an add-on by mamenr, automates a dual-mesh setup so you can sculpt symmetrically on the rest pose while previewing the posed result side-by-side.
Selecting a posed mesh splits the current view or opens a new window, isolating a clean, un-posed model on one side and keeping the posed preview on the other. The add-on prepares Multiresolution modifiers, and a single panel click raises subdivision levels on both the sculpt and pose models at once to prevent topology mismatch.
Detail syncing is manual: pressing Force Sync Details projects your sculpted forms onto the posed model, which the developer describes as a way to keep background lag out of the viewport. When you finish, you can safely unlink the models. The sculpt mesh isn't deleted; it's timestamped, hidden, and archived as a backup you can clone and restore from the panel.
Sculpt Pose Sync is best for blender artists sculpting symmetrically on rigged, posed characters who want to keep the posed deformation of muscles or clothes in view while they work.
Sculpt Pose Sync is completely free to download and use.
Sculpt Pose Sync lists compatibility with Blender 4.2 LTS and newer, so it runs on that release and later versions. You can add it by dragging and dropping the downloaded add-on into Blender, or by installing it from disk through the extensions preferences. The current version is 34.0.0, published in June 2026. If you run an older Blender release, the add-on falls outside its stated compatibility range, so moving to 4.2 LTS or later is the safer path before installing it.
Sculpt Pose Sync is listed as free here in the catalog, and it's distributed under the GNU General Public License v3.0 or later. For the current licensing terms and any changes, check the developer's page. The add-on also states that it requires no special permissions, so it doesn't ask for extra access when installed. For issue reports and the latest details, the developer maintains the sculpt-pose-sync repository on GitHub.
Sculpt Pose Sync uses a strict manual detail sync rather than constant background updating. While you sculpt on the clean, un-posed model, the posed preview stays as it is until you choose to update it. Pressing Force Sync Details projects your sculpted forms onto the posed model on demand. The developer describes this manual approach as a way to keep background lag out of the viewport, so the sync happens only when you ask for it instead of running continuously.
Sculpt Pose Sync doesn't delete your sculpt mesh when you finish and unlink the two models. Instead, the mesh gets timestamped, hidden, and archived as a backup. If you need an earlier state later, you can clone and restore any previous version directly from the add-on's panel. This archiving step is part of the safe disconnect workflow, so unlinking the sculpt and pose models keeps your work available rather than removing it from the file.
