Conversation
Unity talks straight to the BlenderMCP addon socket, so a Blender to Unity handoff is one blender_bridge call: export (GLB/FBX) from Blender, import through the shared model pipeline, place in the open scene and normalize the size from measured bounds. Other actions: status, scene/object info, viewport screenshot, run Python in Blender, check the blender-mcp checkout for updates, and sync its addon.py into Blender's addons folder. The informational "Blender -> Unity Handoff" row in the Asset Gen tab becomes a real panel: socket host/port with Test Connection, blender-mcp checkout and Blender addons dir (Select/Clear, resolved path and addon-in-sync state), and Sync Addon / Check Updates / Import Selection buttons. Settings live in EditorPrefs under MCPForUnity.Blender.* via BlenderBridgePrefs; no machine-specific defaults. BlenderDetection gains user addons dir discovery. Menu items under Window/MCP for Unity/Blender Bridge drive the same handler.
Registers blender_bridge in the asset_gen group with typed parameters that map to the C# handler (snake_case to camelCase, None stripped), and adds the `unity-mcp blender` CLI group (status, scene-info, object-info, screenshot, run-python, import-model, check-updates, sync-addon).
…ection Python: registration group, parameter mapping, non-dict result handling and CLI flag mapping. Unity EditMode: framing-free JSON parse/unwrap, handler validation errors that need no Blender, and PickAddonsDir/ParseVersion.

In `@MCPForUnity/Editor/Services/Blender/BlenderSocketClient.cs`:
- Around line 115-117: Update Unwrap to accept only explicit success and error
statuses: preserve the existing BlenderCommandException for error, return the
result only for success, and throw a protocol exception for missing or unknown
statuses. Add a test covering an unknown status response.
In `@MCPForUnity/Editor/Tools/Blender/BlenderBridgeTool.cs`:
- Around line 145-150: Canonicalize the output directory in the path-handling
flow around ProjectRoot, Directory.CreateDirectory, and File.Copy using
Path.GetFullPath. Reject output_folder unless its resolved path equals the
canonical Assets directory or is within that directory as a child, then use the
validated canonical destination for directory creation and copying.
- Line 271: Update the Blender bridge generation flow around the output
placeholder and related sequential replacements to build a single configuration
object, serialize it once into a safely escaped Python string literal, and parse
it inside the generated script before using its values. Ensure apostrophes and
placeholder-like content such as __APPLY__ remain unchanged, and add a
regression test covering the name O'Brien.
- Line 200: Update the targetSize assignment in BlenderBridgeTool so an explicit

zero keeps the imported scale; avoid converting nonpositive target values to 1f
before the shared importer receives the request.

- Line 22: Update the tool group declaration near group="asset_gen" to use one
of the approved taxonomy values: core, vfx, animation, ui, scripting_ext,
testing, probuilder, profiling, or docs; keep the generated documentation and
related tool metadata consistent with the selected group.
- Line 63: Keep the public parameter name format in the relevant import_model
signature, and add a targeted Ruff A002 noqa suppression to that parameter
declaration only. Do not rename the parameter or broaden the suppression to
unrelated code.

- Run socket and git work on the thread pool: HandleCommand is async, the panel and menu await it, and Unity API calls happen after the await on the editor thread. Buttons are disabled while a call is in flight. - BlenderSocketClient takes an explicit BlenderEndpoint (EditorPrefs is main-thread only) and rejects responses whose status is neither success nor error instead of returning a null payload. - Canonicalize screenshot output_folder through AssetGenPaths so "Assets/../x" cannot escape the project. - Pass target_size through unchanged; 0 now keeps the imported scale as the CLI documents (the pipeline only rescales when > 0). - Embed export-script values as one JSON literal parsed inside Blender, so names with quotes or placeholder-looking text cannot alter the program. - Suppress Ruff A002 on the public `format` parameter. - Document the existing asset_gen group in CLAUDE.md, dev-setup and the tool-groups guide. - XML docs on the new C# members; tests for invalid status, output_folder traversal and the export-script builder.

… compare - import_model: auto_animate (default on) creates a looping AnimatorController next to the asset with one state per imported clip and assigns it, so a rigged model moves instead of sitting frozen with a null controller; FBX clips are marked looping on the importer first. save_prefab stores the placed instance under <asset folder>/Prefabs. ensure_bloom enables camera post-processing and adds a Bloom override to the global volume (through manage_graphics) when the model has emissive materials. - New actions: compare_screenshot composites Blender's viewport (left) and a Unity capture framed on the placed object (right) into one PNG; setup_bloom runs the Bloom setup on its own. - Export prefers the addon's export_scene command (validated parameters, no code execution) and falls back to the execute_code script on older addons. - Python tool, CLI (--no-animate, --save-prefab, --ensure-bloom, compare-screenshot, setup-bloom), tests and generated docs updated.

Thanks, very interesting idea! Can you run a version-based api audit across the code to make sure this would not cause any issues on other versions of Unity? For example, UnityEngine.UIElements was UnityEditor.UIElements in Unity 2021.3. |
…3 floor Object.FindObjectsByType(Type, FindObjectsSortMode) only exists from 2023.1, so setup_bloom did not compile on the package's minimum Unity versions. Route the lookup through the existing compat shim, which dispatches to FindObjectsOfType before 2022.3 and to the current API afterwards.
…21.3 IntegerField is editor-only (UnityEditor.UIElements) on the 2021.3 floor and only moved to UnityEngine.UIElements in 2022.1, so the Blender Bridge panel failed to compile there. A TextField with int parsing resolves identically across the supported range.
The verbatim template inherits the checkout's line endings, so a CRLF checkout produced a CRLF script and broke the builder tests on Windows.

Description
MCP for Unity already ships an informational "Blender → Unity Handoff" row in the Asset Gen tab and a
blender-to-unityskill, but the handoff itself still needs an AI client to orchestrate BlenderMCP and MCP for Unity step by step: export viaexecute_blender_code, thenimport_model_file, then place, then measure bounds and rescale. That is six manual steps for the most common DCC → Unity round trip, and it does not work at all without an AI client attached.This PR lets the Unity Editor talk to the BlenderMCP addon socket directly, so the handoff is one
blender_bridgecall, and gives the feature a real settings panel in the existing Asset Gen tab. Menu items drive the same handler, so it also works with no AI client connected.Type of Change

Additional Notes
Version audit. Following the review request, every Unity, UI Toolkit, .NET and C# construct the branch adds was audited against the CI matrix and the full EditMode suite was run per version. It found two real problems on the floor, both fixed here:
IntegerFieldis still editor-only (UnityEditor.UIElements) on 2021.3 and only moved toUnityEngine.UIElementsin 2022.1, so the panel did not compile there. The port field is aTextFieldwith int parsing, which resolves identically across the whole range.Object.FindObjectsByType(Type, FindObjectsSortMode)in the Bloom setup only exists from 2023.1. It now goes through the existingUnityFindObjectsCompat.FindAll(Type)shim, so no new#if UNITY_*branch was added.A Windows-only test flake surfaced on the way: the generated Blender export script inherited the checkout's CRLF, so the template is now normalized to LF.
Everything else the branch relies on (
AssetDatabase.*,PrefabUtility.SaveAsPrefabAssetAndConnect,ModelImporter.clipAnimations,AnimatorController.CreateAnimatorControllerAtPath,AnimationUtility,ImageConversion.LoadImage,EditorPrefs) has existed since 2019 or earlier with no renames across the matrix. URPVolume/UniversalAdditionalCameraDataare reached throughType.GetTypereflection andmanage_graphics, so there is no compile-time dependency on URP or HDRP and the action degrades to "nothing to do" when the assembly is absent. The Python side usesdict[str, Any]andX | None, matchingrequires-python >= 3.10.Unity 6000.5. The package compiles, but the existing test assembly does not: several tests under
