HueForge 0.9.3 Release Notes

The "Bugfix Build" got a lot bigger.

Surprise! ColorDrop Plugin Released with HueForge 0.9.3

Get More Details Here

Also checkout out - About HueForge and check out the Mesh Modes descriptions for help understanding how HueForge works.

In the meantime, some of you love release notes so… these are for you.

Currently Release for Windows/MacOS. Linux hopefully early this coming week before RMRRF. That’s the plan. It’s building but way under tested.

You WILL need to download the updates for HugeForge and FlatForge to keep them working

HueForge 0.9.3 Release Notes

SpotFix — New Feature

SpotFix is a new tool for making targeted height adjustments directly on your model.

Click any region in the 3D view to create a SpotFix, then adjust it up or down by layer to fine-tune problem areas — without touching your source image.

Key Capabilities

• Region-based selection — Click to select a color region; Ctrl+Click to expand to adjacent regions

• Layer delta control — Push regions up or down by layer count (+ / -)

• Flatten modes — Snap a region to a specific layer instead of nudging (F to cycle)

• Inside-loop fill — Fill enclosed regions like letters or shapes (I to toggle)

• Eyedropper — Sample a target layer from another part of the model (E)

• Tolerance control — Adjust how aggressively regions are selected (W / S keys)

• Undo / Redo — Full undo stack within SpotFix mode (Ctrl+Z / Ctrl+Y)

• Non-destructive — SpotFixes are saved in your project and adapt automatically when layers or size change

SpotFix Hotkeys

• Click — Create new SpotFix at cursor

• Ctrl+Click — Add region to selected SpotFix

• / - — Adjust layer delta

• F — Cycle flatten mode between the most common, top or bottom layer of the selection.

• I — Toggle inside-loop fill (only after clicking)

• Del — Delete selected SpotFix

• Ctrl+Z / Ctrl+Y — Undo / Redo

• Esc — Deselect

• W / S — Adjust tolerance (above / below)

• 0 — Reset tolerance

The SpotFix toolbar button shows an amber indicator when fixes exist in your project.

Project Tree — New Feature

Project Tree introduces a visual branching history for your project.

You can capture snapshots at any point and move freely through your edit history without losing work.

Features

• Automatic snapshots on mesh mode changes and Project Save

• Named snapshots with custom labels

• Searchable snapshot list

• Visual branching graph

  • Blue paths = undo history

  • Green dashed paths = redo branches

• Separate User Tree (manual saves) and Autosave Tree (automatic captures)

Keyboard Shortcuts

• F4 — Create named snapshot

• F5 — Quick snapshot

• F7 — Navigate backward (undo path)

• F8 — Navigate forward (redo path)

• F10 — Toggle Project Tree panel

---

Filament Library Improvements

• Favorites — Mark filaments for quick access at the top of each category

• Active Filaments — Currently used filaments grouped together automatically

• Import / Export Personal Library — Move your filament collection between machines (JSON format)

• Preview on import — See what will be added, updated, or unchanged before applying

• CSV import fix — Missing optional fields no longer cause rows to be dropped

• Safer saves — Atomic writes prevent corruption during crashes

---

Mesh Optimization

Flat surface regions are now heavily optimized.

Uniform flat areas are merged into larger triangles instead of using a full per-pixel grid, dramatically reducing file size with no visible quality loss.

Optimization is uniformly applied to all output. Modes like FlatForge will not benefit as much given the non-flat mesh geometry.

---

Background Removal

The old manual background removal step is gone.

Transparent image backgrounds are now automatically excluded from mesh geometry across all save paths with optimized bottom mesh layers.

---

Performance Improvements

• Luminance calculation — 4–7x faster (multi-core)

• Height updates — 2–4x faster

• Mesh generation & splitting — Significantly faster

• Project load — Eliminated redundant rebuilds (previously 2–3x per load)

• SVG rendering — Now re-rendered from vector source at target resolution (no pixel upscaling)

---

Color Matching Improvements

• HSV matching — Much more accurate for stylized and illustrated images

• Dot Product matching — Improved performance for photographic images

---

Stability Fixes

Fixes across:

• Out-of-bounds and null dereference crashes when moving sliders on the Color/Mesh Core

• Sliders — Undo behavior corrected; handles update immediately

• Project loading — No longer drops filaments used across multiple sliders

• OpenGL — Fixed texture leaks, validation errors, and deprecated usage

• Shutdown — Fixed hanging processes (Windows) and exit crashes (macOS)

• Background tasks — Proper cleanup before shutdown

• macOS — Fixed incorrect default config directory on fresh installs

Other Improvements

• First Layer Height — No longer required to be a multiple of layer height (plugins + advanced options)

• Named Defaults — Save and manage multiple default project configurations

• Help/Tutorial Menu — Now supports live-updatable content

• Borders now save properly when saving with Advanced mode. Though still no borders for non-rectangular models.

HugeForge Plugin v1.1.2

This release adds a new Checkerboard Tiling Mode, improves borders and spacing behavior, adds destructive crop support, and fixes several reliability and sizing issues.

Checkerboard Tiling Mode — New

A new tiling mode for creating staggered layouts such as chess boards, mosaics, and decorative wall panels.

• Checkerboard mode places tiles in an offset grid, with odd rows shifted by half a tile width

• Max Per Row and Total Tiles controls for tighter layout control

• Square Tile option to lock tile width and height together

• Skip First Tile option to invert checkerboard parity for generating the second color set

• Rotate Source 90 to rotate the image before tiling

• Image Offset slider to shift the crop window when tiles do not perfectly cover the image

• Smart tile size defaults auto-calculate when switching to Checkerboard mode based on project dimensions

• In-app help added with a ? button next to Checkerboard mode, including SVG diagrams and chess board setup instructions

Borders and Spacing

• External borders for tiled prints now extend around the full assembled piece instead of only individual tiles

• Partial borders can be applied per tile edge, such as outer edges only for interior tiles

• Border on each tile option added for Checkerboard mode to apply full-frame borders to every tile

• Tile spacing is now reflected in final assembly dimensions, including border width

Destructive Crop

• Crop spacing from image now permanently crops the image at tile boundaries, creating image gaps between tiles.

• Final size calculations now correctly account for both destructive crop and border width

State and Reliability

• Persistent state for HugeForge settings is now saved and restored when you reload your project.

• Tile generation stabilized with fixes for stalls, spike removal timing, and empty-layer crashes

• Split-state resilience improved for interrupted or partially completed tile exports

Fixes

• Fixed settings not persisting between dialog opens

• Fixed resize handling when switching between modes

• Fixed tile size snapping by using round instead of truncate to avoid floating point precision loss

• Removed limitation on Base Layer Height being a multiple of the layer height.

FlatForge Plugin — Release Notes (v1.1.2)

Layer Gap Stitching

• The biggest quality improvement for FlatForge prints. Previously, separated color layers could have visible gaps at boundaries where layers meet. Fewer gaps in flat surface.

• FlatForge meshes are now completely watertight and should work with Mesh Booleans and not just Negative Modifiers.

Performance

• Parallel mesh generation — layer meshes are now built concurrently across threads, with a 2 GB memory budget to prevent OOM on large models

• Per-mesh progress reporting — progress bar updates for each layer as it builds

• 8.7x faster HeightMap setup

• Reduced mesh allocation overhead

Memory

• Preview meshes freed before export — halves peak memory during STL generation

• Dialog close cleanup — FlatForge meshes, heightmap data, and preview data are all released when the dialog closes, fixing memory leaks that accumulated with repeated use

• Null guard on setHeightMapData to prevent crashes

Other Changes

• Fixed cap layer z-position using consistent zSpacing

• Fixed double-sided export and folder path handling

• Background removal (cutout) now happens by default — removed the separate CutoutSession
