Bbrush sits at rank 128 in the blender_extensions library. It's written entirely in Python and released under the GNU General Public License v3.0 or later, with support offered through the developer's Discord channel. Worth noting the documented caveats: silhouette display doesn't yet work in Blender 4.5, switching hidden faces disables multiresolution, and the developer flags a crash from combining Blender 3.0, smooth brushes and inverted sculpting.
Bbrush is a Blender add-on from ACGGIT_LJ that simulates the way ZBrush sculpts. Built for tablet artists, it can be worked using only a pen and keyboard. You select a mesh object to enter sculpt mode, then enter BBrush Sculpting mode either manually or automatically alongside sculpt mode through the preference settings, with the shortcut keys shown on screen.
Once in sculpt mode, a Bbrush mode button appears in the top bar. Bbrush mode covers a Normal mode showing frequently used brushes, a Mask mode where the brush switches to a mask brush, and a Hidden mode for hiding and revealing faces. Shortcuts handle view manipulation, sculpting, smoothing and a wide range of mask operations. The silhouette display can be set to Always, Only Sculpt, Only Bbrush or Disable, with an adjustable scale.
A couple of caveats are documented: silhouette display does not currently support Blender 4.5 because the API is not ready, and switching hidden faces disables multiresolution. Bbrush is compatible with Blender 4.4 and newer and released under the GNU General Public License v3.0 or later.
Bbrush is best for tablet artists sculpting in Blender who want a ZBrush-style workflow driven by pen and keyboard shortcuts, with an on-screen silhouette to guide the form.
Bbrush is completely free to download and use.
Bbrush is compatible with Blender 4.4 and newer, so current Blender releases should run it. One caveat to keep in mind: the silhouette display does not currently support Blender 4.5, since the required API is not yet ready. The sculpting, masking and hiding features are unaffected by that limitation. If you rely on the silhouette specifically for tablet work, check the developer's GitHub page for the latest status before moving to 4.5.
Bbrush can be set to turn on automatically alongside sculpt mode through its preference settings, or you can enter BBrush Sculpting mode manually. The usual flow is to select a mesh object, enter sculpt mode, then activate BBrush Sculpting mode, with the shortcut keys displayed on screen. Once you are in sculpt mode, a Bbrush mode button appears in the top bar, giving access to Normal, Mask and Hidden modes.
Bbrush is listed as free here in our catalog and is released under the GNU General Public License v3.0 or later. That license governs how you can use, modify and redistribute the add-on. For the most current licensing terms and any changes, check the developer's GitHub page. If you run into problems or have suggestions, the developer also points users to a Discord channel for support.
Bbrush comes with two documented caveats worth knowing before you dig in. Switching hidden faces will cause multiresolution to be disabled, so plan around that if your workflow depends on a multiresolution modifier. The developer also notes that combining Blender 3.0, smooth brushes and inverted sculpting can cause a crash. Keeping these in mind can save you from unexpected behaviour mid-session. For updates on these issues, the developer's GitHub page is the place to check.
Bbrush can be added by dragging and dropping the add-on into Blender, or by downloading it and installing from disk through Blender's extensions preferences. After installing, select a mesh object to enter sculpt mode, then enter BBrush Sculpting mode to begin. The extension requests permissions covering file access, view navigation and texture loading, so you can see what it touches before installing. If you hit any issues during setup, the developer points users to a Discord channel for help.
