Release notes

Version 1.3.0

Released: September 19, 2026

This release adds native Tridi project files and new viewing controls, with sharper wireframe rendering and more reliable project saving.

New

• Added native Tridi Project (.tridi) files with Save, Save As, unsaved-change protection, and Ctrl+S for reopening editable viewer sessions.
• Added non-destructive Scene Scale presets from 0.01x to 1000x and automatic camera Turntable mode with T.
• Added configurable shortcuts for Solid Wireframe (Z), Reload (Shift+R), and Revert (Ctrl+Shift+R).

Improvements

• Solid Wireframe now stays sharp independently of the shaded viewport anti-aliasing.
• Improved project save reliability, especially for large projects and embedded images, with more consistent unsaved-change and undo behavior.

Version 1.2.1

Released: September 13, 2026

This patch covers end-user changes since version 1.2.0.

New

• Added an optional Use Geometry Names setting for Auto Find Textures, helping models with generic or unreliable material names find the correct texture sets.

Improvements

• Improved PBR edge stability with specular anti-aliasing and reduced selection-highlight rendering work when the scene is unchanged.
• Loaded models now show their source filename in the application window title.
• Improved material-asset portability by saving supported material images as lossless PNG files.

Fixes

• Fixed reload timing so undo and redo history is cleared only after a geometry reload commits successfully.
• Fixed geometry reloads and texture edits so compatible material images, texture factors, presets, and exported results remain consistent.
• Fixed glTF and GLB export portability, morph-position bounds, unsafe oversized self-contained glTF output, and unsupported sampler handling.
• Fixed Toon outlines activating for transparent or zero-width source outlines and preserved authored width when editing only the outline color.

Version 1.2.0

Released: September 12, 2026

This release covers end-user changes since version 1.1.3.

New

• Added application-wide undo and redo for selections, visibility, scene orientation, viewer settings, material properties, textures, and presets with Ctrl+Z and Ctrl+Shift+Z.
• Added mouse box selection with live object and material previews, available with B.
• Added PBR, Unlit, and Toon shading controls plus editable Toon shadows and outlines, normal strength, alpha cutoff, thickness, transmission, IOR, attenuation, anisotropy, iridescence, and dispersion.
• Added configurable shortcuts for cycling visible render channels with C and toggling a chrome-free Full Window view with Tab.
• Added background Microsoft Store update checks and in-app optional or required update flows for packaged builds.

Improvements

• Improved object, material, and UV selection with multi-material selection, synchronized per-face UV filtering, clearer transient highlights, and configurable highlight opacity.
• Expanded Auto Find Textures to every supported material slot and common packed-map layouts, with better shared FBX texture discovery and embedded-alpha recovery.
• Reload Model now refreshes geometry while preserving compatible material edits, textures, selections, and visibility.
• Improved viewport navigation with Shift+right-drag environment rotation, a wider mouse-zoom range, and better zoom limits for large scenes.

Fixes

• Fixed malformed glTF animation timelines so usable keyframes continue to play.
• Fixed FBX texture resolution, shared texture-set matching, and alpha handling.
• Fixed object and material selection outlines, transient pulses, and Select All behavior in overlapping or hidden-highlight states.
• Fixed shortcut capture conflicts and continuous-edit undo transactions in Preferences and material controls.

Version 1.1.3

Released: September 5, 2026

This hotfix covers end-user fixes since version 1.1.2.

Fixes

• Fixed Unicode model and texture paths, plus material, bone, morph, and warning names, for PMX and other supported formats.
• Fixed glTF sheen and specular textures, UV sets and transforms, scalar channels, and high-dynamic-range specular colors across import, rendering, material editing, and export.
• Fixed supported glTF material extensions being reported as unsupported.
• Fixed some FBX materials appearing self-illuminated because ambiguous legacy emissive values were treated as authored emission.
• Fixed automatic transparency after texture edits so mixed opaque, cutout, and translucent regions rebuild immediately and return to the correct automatic blend state.
• Fixed panel dropdowns and color pickers being obstructed by dock separators, and fixed sliders losing their drag when the pointer moves outside the window.

Version 1.1.2

Released: September 4, 2026

This patch covers end-user changes since version 1.1.1.

New features

• Added a per-material Double Sided control, including an option to restore the source-authored value.
• Added a dockable Model Error panel that collects model-loading errors and warnings and can copy the complete diagnostic list.

Improvements

• Improved FBX material accuracy for emission, opacity and transparency, reflection and specular response, height and displacement, and scalar texture channels.

Fixes

• Fixed FBX morphs so supported targets and animation remain available when individual source channels are unusable, while the initial pose no longer applies every facial expression at once.
• Fixed mixed opaque, cutout, and translucent triangles within one textured primitive so each region uses the correct depth and transparency behavior.

Version 1.1.1

Released: September 1, 2026

This patch covers end-user changes since version 1.1.0 Beta 3.

Improvements

• Material Properties image controls now follow each channel's effective image automatically, with clearer Select image and No image loaded states plus a compact unlink action.
• Improved texture consistency across import, material editing, previews, render passes, presets, and model export, especially for images shared by multiple material channels and packed channel data.
• Improved PMX compatibility by retaining usable geometry and hierarchy when optional source corrections cannot be applied, preserving skinning in morph buffers, and keeping authored material names, opacity, specular/roughness intent, sidedness, and textures.
• PMX files with missing external textures now retain usable untextured materials and report one clear combined warning.

Fixes

• Fixed shared alpha atlases so opaque, cutout, and translucent primitives can use the correct depth and transparency behavior even when they share one source material.
• Fixed authored Blend materials being overwritten by texture analysis while still selecting optimized runtime behavior for each primitive.
• Fixed transparent surfaces to use the appropriate one-sided or two-sided two-pass rendering, and fixed thin versus solid transmission selection to follow material thickness.
• Fixed Material Properties image-dropdown scrolling and aligned active image-control feedback with the primary interface color.

Version 1.1.0 Beta

Released: August 30, 2026

This release covers end-user changes since version 1.0.1 Beta 1.

New features

• Added a session-only UV workspace with UV0/UV1 viewing, object selection and highlighting, surface-aware render passes, pinch zoom, and an optional wireframe overlay.
• Added OBJ export. Choosing an OBJ filename creates a named folder containing the OBJ, MTL, and referenced texture maps.
• Added a selected-material properties panel with texture-channel navigation, UV tiling controls, blend-mode control, and sheen, specular, and clearcoat material controls.
• Added resizable left and right workspace docks. Panels can snap into either side, use independent widths, and the Dimensions panel can be detached.
• Added broader Unicode text rendering for model names, paths, and interface content.
• Added an opt-in experimental Mesh Validator under Preferences > System, with Entire Scene and Selected Objects validation scopes and an F5 panel shortcut while enabled.

Improvements

• Replaced the experimental multi-model comparison workflow with one current model and the dedicated UV workspace. Opening another model now replaces the current model.
• Improved source-wireframe and dynamic-topology performance.
• Improved OpenUSD material texture processing.
• Improved material and object panels, status-bar presentation, playback-bar placement, viewport auto-hide transitions, tooltips, and narrow-window layout.
• The in-app Beta Notice now links directly to the public beta notice and release notes.
• Unsupported optional PMX morph types are now skipped when a usable model can still be loaded.

Fixes

• Fixed a crash when reloading a model while UV rendering resources were active.
• Fixed OBJ face groups appearing as separate objects and removed unused materials from exported files.
• Fixed UV seams after Assimp vertex joining, UV focus centering, UV presentation, wireframe ordering, and touch pinch sensitivity.
• Fixed object visibility synchronization between the 3D and UV views.
• Fixed fractional UV tiling edits, material source-mode synchronization, material-card touch scrolling and thumbnail interactions, and numeric field selection on repeated clicks.
• Fixed selection outlines and viewport overlays being clipped or layered incorrectly around docked panels.
• Fixed the Windows system beep triggered by Alt-based shortcuts.

Documentation compatibility

Feature and format pages describe verified behavior for version 1.3.0 public beta. Import support is defined by the documented subset for each format; recognizing an extension does not imply complete support for every feature in that format.
