Checks that Blockbench is open, the Stonecut Bridge plugin is listening and the token is right. Returns the plugin version.

Whether the GeckoLib plugin is installed, the allowed folders (output, assets), the open project (format, bones, cubes, textures, animations, and for Java models the display transforms) and every open tab with its edit count. Call this first.

Opens a new tab with an empty GeckoLib animated entity model (a Bedrock entity model if the GeckoLib Blockbench plugin is missing; the reply then has a warning). 16 units = 1 block; the model stands on y=0 and faces north (-Z).

Opens an existing Bedrock/GeckoLib .geo.json in a new tab (converted to GeckoLib format when that plugin is installed), optionally with its .animation.json and texture PNG. If the file is already open it switches to that tab instead.

Closes extra copies of a tab, keeping the first. A copy is closed only when it matches the kept tab (name, format, element and texture count) and has no edits, so no work is lost.

Adds bones (groups). Only bones animate, so every GeckoLib cube goes in a bone. Start with one root bone, then body, head, legs... with pivots where the joints are. Names must be unique. Nothing is created if any entry is bad.

Adds cubes. Give "from"+"to" or "origin"+"size". GeckoLib models use box UV: give each cube its own uv_offset so UV islands do not overlap. Java models may use "faces" for per-face UVs and need no bone. Nothing is created if any entry is bad.

Creates the project texture, or resizes it (the canvas grows or shrinks and old pixels stay at the top-left). Also sets the project UV size unless set_uv_size is false.

Fills a rectangle of the texture with one colour (or clears it).

Sets single pixels: a list of [x, y, colour].

Draws a small picture from rows of characters, for example rows ["..ab..", ".abba."] with palette {"a": "#ff0000", "b": "#000000"}. Characters not in the palette are skipped. Each character covers scale x scale pixels.

Loads a PNG from the output or assets folder as the project texture.

Adds an animation, for example idle, walk or attack. Looping animations should end on the pose they start with.

Adds keyframe tracks to an animation: per bone and channel (rotation in degrees, position in units, scale as factors).

Renders the 3D preview from named views (or yaw/pitch in degrees) and returns the images; PNG files are also written to the output folder. The camera frames the model and is put back afterwards. "right" is the model's right side when it faces north. Give animation + time to see a pose. Screenshot often and check every side.

Writes the open project: geo (.geo.json, GeckoLib/Bedrock), animation (.animation.json with all animations), model (Java block/item .json with its display block, Java projects only) and texture (.png). Existing files are kept unless overwrite is true.

Opens a Java block/item model .json that has "elements" in a new tab. Its texture comes from "texture", a same-named PNG next to the model, or assets/textures/...; anything else shows blank. Parent models are not followed. If the file is already open it switches to that tab.

Opens a new tab with an empty Java block/item model, for example a weapon. Cubes need no bones. Optional display transforms, given directly or copied from a preset file.

The display transforms of the open Java model: every set slot, or one slot.

Sets display transforms (undoable). Give "display" for several slots, or "slot" with rotation/translation/scale, or a "preset" file. Fields you leave out keep their value unless replace is true.

Renders display slots as the Blockbench display editor shows them and returns the images (PNG files also go to the output folder). First person is uncropped by default so you see how much of the view the item takes; gui is the inventory square.
