Lumina Studio 2.0 Development Report: August 2026

August improved continued editing, material color consistency, backing settings and complex SVG exports. This report covers completed and merged work; installer notes identify changes available in each version.

Projects and selection

Projects retain source artwork, output settings, whole-image recoloring and custom-recipe history for later comparisons. Spatial edits still had session-only limits at this stage; October added complete saving of local edits, regional recipes and selections.

Shared selection, a brush and checkpoint undo allow tools to act on one selected area, with visible edges. Clearing the selection after applying a recipe does not remove the confirmed edit.

Materials and backing

• Complete dynamic layer handling across matching, preview and generation.
• Use consistent simulated colors for the same filament stack in conversion, custom recipes, achievable colors and material queries.
• Extend backing thickness to 10 mm and add deeper-backing infill control, retaining a solid zone near the viewing face.
• Correct backing/color-layer alignment, semitransparent PNG matching and large-format backing modifiers.

Consistent simulation does not eliminate physical color differences. Measurements, calibration and printing conditions still matter.

Devices and exports

• Reorganize settings and improve device artwork and high-resolution display.
• Select native build plates, remembered by slicer and printer.
• Add QIDI Studio support within the application's machine/nozzle list.
• Optionally use uploaded names for ordinary single-model exports; other workflows keep their own naming.
• Continue fixes for cross-slicer wipe-tower layouts, mirrored puzzle assembly and material-slot identity.

SVG and previews

Several rounds address slow first analysis, high memory use, open outlines and lost hole details. Color-region and material solving use parallel work with bounded intermediate memory.

Browser previews begin using lighter representations instead of complete print meshes. September extends this approach to more workflows. The lighter display does not replace the precise downloadable 3MF.

Creative workflows and continued work

Validate base meshes before model-surface generation and correct vertical artwork movement and orientation. Align relief brightness with height and correct heightmap drag-and-drop. Extend Workshop installation/management and retain the native bead-pattern handoff.

Complex boundaries, inner/outer shells and slicer-precision geometry still need real slicing checks. September continues this work. Reverted intermediate geometry changes are not delivered features, and no universal speed multiplier is claimed.
