Sculpt Stack earns its place for bringing a familiar layer-based sculpting workflow natively into Blender's sculpt mode. It was built by a working 3D environment artist for their own daily use and refined on real production meshes.
In Blender, every sculpt stroke is permanent the moment you make it. Sculpt Stack changes that by bringing a layer-based sculpting workflow natively into Blender's sculpt mode. You capture sculpt passes as independent, blendable layers, then dial each one's strength up, down, or off with a slider at any time. Nothing is baked until you choose to bake it.
To start, you select your mesh, open the Sculpt Stack panel, and press Activate Sculpt Stack, which freezes your current mesh as the base. It works on a clean mesh or one that already carries sculptural detail. From there you sculpt a pass with any standard brush, bank it as a layer with one button or the hotkey, and blend passes independently. A master opacity control scales the whole stack at once, and per-layer masking lets a pass affect only part of the mesh.
Sculpt Stack was built by a 3D environment artist and tested on real production meshes. Vectorized evaluation keeps blending responsive on dense sculpts, and Subdivision and Mirror modifiers display normally over your layered result.
Sculpt Stack is best for blender artists who want to adjust the strength of sculpt passes after the fact and blend them non-destructively, rather than re-sculpting by hand.
Sculpt Stack is completely free to download and use.
Sculpt Stack works alongside Blender's Subdivision and Mirror modifiers, which display normally over your layered result. That means you can keep those modifiers active while banking and blending sculpt passes, seeing your layered work reflected through the modifier stack. Blending stays responsive on dense, production-scale sculpts thanks to vectorized evaluation, so working on high-resolution meshes with modifiers applied remains practical rather than sluggish. This lets you sculpt in layers while still previewing the mesh as it will appear with your usual modifier setup.
Sculpt Stack captures a sculpt pass as a layer with a single button, Bank Pass, or a customizable keyboard shortcut set to Ctrl+Shift+B by default. You bank without leaving sculpt mode, so you sculpt normally with any standard brush, press the shortcut to capture what you sculpted, then sculpt more and bank again to build up a stack. Each banked layer gets its own weight slider that you can drag at any time to blend that pass's strength up or down.
Sculpt Stack handles per-layer masking with Blender's native Mask brush, so there's no new tool to learn. You select a layer, paint your mask, and preview the masked result before committing, with the mask paint hiding during preview so you can see the result clearly. Once it looks right, you bake the mask into the layer. This lets a single pass affect only part of the mesh, such as confining a fine detail pass to a specific region.
Sculpt Stack is maintained by a working environment artist who updates it as Blender evolves. When a new Blender version releases, you log into your account and download the latest build. For questions or bug reports, you can message the developer directly through the Superhive inbox, where they read every message and aim to respond within 72 hours. That direct line covers both ongoing compatibility updates and help when something isn't behaving as expected.
Sculpt Stack is listed as free here in our catalog. For current licensing details, check the developer's page, since terms can change over time. To use it, you activate the tool on a selected mesh to set your base, then sculpt and bank passes as layers. The developer, Studio Sphaerus, distributes builds through Superhive, where you log into your account to grab the latest version when a new Blender release arrives.
