It has 54 slots in six rows of nine. Slots are numbered from 0 at the top left, the same numbers as the labels in the pictures below. The palette has five slots, numbered 1 to 5 in the menu, which are slots 46 to 50 of the menu. Review note: this table is written by hand from the section comments of `GUI.java` and the click handler of `InventoryListener`. The pictures are generated from the code. When the layout changes, update this table and regenerate the pictures with `./gradlew generateDocsImages`. ## Pictures The default settings, with the Sphere Brush selected: ![Brush menu with the Sphere Brush and default settings: the brush item in slot 10, the mask on in slot 15, and one stone block in palette slot 1](https://862810040-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3dAk0UjgUbQUOWgnpUwe%2Fuploads%2Fgit-blob-5bfd0668a3bc3f53d2759887cb64cf96145c3234%2Fmenu-sphere-default.svg?alt=media) The Angle brush, with its two extra settings in slots 12 and 13: ![Brush menu with the Angle Brush: Angle Check Distance 2 in slot 12, Maximum Angle 40.0 degrees in slot 13](https://862810040-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3dAk0UjgUbQUOWgnpUwe%2Fuploads%2Fgit-blob-1460bcdc8103456d30d49c72a399f3a590620a59%2Fmenu-angle.svg?alt=media) The Spray brush with the mask turned off and two palette blocks: ![Brush menu with the Spray Brush disabled and the mask off: the Mask item in slot 15 is a carved pumpkin, and the Current Mask in slot 52 is dirt](https://862810040-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3dAk0UjgUbQUOWgnpUwe%2Fuploads%2Fgit-blob-a8a83e597b68fd2ad8ef7c23836780a983ddd9b5%2Fmenu-spray-disabled.svg?alt=media) ## Slots | Slot | Item | Shows | Click | | -------- | ------------------------------------- | --------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------- | | 10 | Brush item (feather, "goPaint Brush") | Enabled or Disabled | Right-click toggles the brush. Left-click with a non-block item that is not the brush item stores the brush on that item. | | 11 | Selected Brush type | The brush list, the selected brush highlighted | Left-click: next brush. Right-click: previous brush. Shift-click: brush picker. | | 12 | Setting 1 of the brush | See the table of settings below | Left-click raises, right-click lowers. Disc brush: click cycles the axis. | | 13 | Setting 2 of the brush | Maximum Angle (Angle brush) or Mixing Strength (Gradient brush) | Left-click raises, right-click lowers. Angle brush: shift-click changes by 15. | | 14 | Brush Size | Brush size | Left-click +1, right-click -1, shift-left +10, shift-right -10. | | 15 | Mask | Enabled (jack o'lantern) or Disabled (carved pumpkin) | Click toggles the mask. | | 16 | Surface Mode | Direct, Relative or Disabled | Click cycles Direct, Relative, Disabled. | | 37 to 41 | Yellow panes above the palette | Nothing | Act as palette slots 1 to 5, as slots 46 to 50 do. | | 43 | Yellow pane beside the palette | Nothing | Left-click with a solid block sets the mask block. | | 46 to 50 | Palette slots 1 to 5 | The block and its chance, or a barrier when empty | Left-click with a solid block adds the block, or replaces it. Right-click clears the slot. | | 52 | Current Mask | The mask block | Left-click with a solid block sets the mask block. | The panes above and below slots 10 to 16 (slots 1 to 7 and 19 to 25) act like the item in their column. All other slots are fillers: a click does nothing. ## Settings and their ranges Steps are per click. Shift-click is listed where it changes the step. | Setting | Item | Range | Default | Step | | ----------------------- | --------------------------------------------- | ------------------------------------------------- | ------- | ------------------- | | Place chance | Spray brush, slot 12 | 10 to 100 % | 50 % | 10 | | Axis | Disc brush, slot 12 | X, Y or Z | Y | cycles X, Y, Z | | Layer thickness | Overlay and Underlay brushes, slot 12 | 1 to 5 | 1 | 1 | | Fracture check distance | Fracture brush, slot 12 | 1 to 5 | 2 | 1 | | Angle check distance | Angle brush, slot 12 | 1 to 5 | 2 | 1 | | Falloff strength | Splatter, Paint and Gradient brushes, slot 12 | 0 to 100 % | 50 % | 10 | | Maximum angle | Angle brush, slot 13 | 10.0 to 85.0 degrees | 40.0 | 5, or 15 with shift | | Mixing strength | Gradient brush, slot 13 | 0 to 100 % | 50 % | 10 | | Brush size | All brushes, slot 14 | 1 to 100 | 10 | 1, or 10 with shift | | Palette chance | Palette slots 46 to 50 | 100 divided by the number of blocks, rounded down | — | — | The maximums of thickness, angle check distance, fracture distance and brush size, and the defaults, can be changed in `config.yml`.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.onelitefeather.net/reference/brush-menu.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
