New Release v2.5.8

Highlights

MeshInspector is now fully translatable — the entire interface, including dialog titles, action names, and auxiliary widgets, can be localized, with a language picker available right from the Quick Setup window on first launch.

This release also adds MCP support, letting AI tools like Claude Code drive MeshInspector directly: open files, run tools, capture screenshots, and even write and execute Python code inside the application. Install the MCP integration →

Updates

Localization

• The UI is now translatable end-to-end — dialog titles, action names, and auxiliary widgets all go through the localization system.
• Language selector in the Quick Setup window. Pick the interface language during first launch — no need to dig through preferences.
• Expanded translations across previously untranslated panels and tools.
• Authentication window translation handling fixed.

AI / MCP Integration

• MCP gateway is shipped with the application, built in and included in the macOS bundle out of the box.
• Python from MCP. AI agents can now write and run Python code directly inside MeshInspector, gated by the Python plugin’s access check.
• Screenshots and shutdown over MCP — viewer.captureScreenshot and viewer.shutdown work even while signed out, so agents can capture results without an active session.
• MCP tool validator runs at install time and gates AI-driven actions for signed-out users.

Mesh Healing & Repair

• Self Intersections repair gains new mimic options in the Advanced section, helping preserve the original surface character during repair.
• Reduce Total Angle option added to RebuildMesh, Make Delone, MeshHealer (on by default), and Offset — produces cleaner triangulations on flat areas.
• Make Delone: more granular control over the remeshing pass.

Selection

• Partitioner — a new tool for mesh segmentation. Splits a mesh into meaningful regions and color-codes each segment for instant visual feedback. Boundary edge type is toggled with icon buttons for a faster setup.
• Select Boundary Edges/Faces is now disabled automatically when the mesh has no holes — no more clicking a tool that has nothing to do.
• Select Component updates correctly when the edge selection changes, and the component visualization has been refreshed.
• Screen lasso auto-closes the polygon more intuitively at the end of a stroke.

Mesh Editing

• Section: when you re-enter the tool with the same objects still in the scene, the previous cutting plane is restored.
• Brush: new mimicPatch option for finer control over patched regions.
• Create Primitive: torus radius is clamped to a safe range to prevent edge-case asserts.

Object Transformation

• Transform multiple selected objects at once. Object Transformation now respects multi-selection, so you can move, rotate, or scale a group of objects together in one operation.

UI/UX

• Quick Start window layout fix on smaller screens.
• Welcome window loads faster: decorative primitive icons no longer go through the test engine.
