HueForge 0.9.3.1 Release Notes
ColorDrop 1.0.2, FlatForge 1.1.3 and HugeForge 1.1.3 also released
HueForge Bugfix Roundup (Apr 11–15, 2026)
This update window was all about reliability. We focused on fixing edge cases that could interrupt workflow, especially around SpotFix behavior, filament library consistency, macOS stability, and render-thread safety.
A few things - Some users have gotten black color cores with zero sliders on them. I’m not sure why this is happening, but the fix is to go to Options→Reset Defaults to Factory
Issues with TD1 License request should also be sorted out. The boot_out.txt now saves properly and the instructions are clearer.
What’s fixed
Saving a Project with Advanced Options but not Split By Color was making a shorter STL than it should. This has been fixed.
SpotFix loop expansion now behaves predictably and no longer over-selects unexpectedly large regions.
SpotFix traversal now respects already-masked regions, enforcing exclusive loop ownership to prevent accidental stacking/over-claiming.
SpotFix undo/redo and merge behavior were tightened so loop edits restore correctly instead of drifting into invalid transparency states.
Transparency/base-thickness mask behavior now survives Min Depth changes correctly.
Active/Favorite filament rows now stay in sync with the main filament list when edited (including ownership/state consistency).
macOS project save permission recovery was hardened so failed writes can recover cleanly instead of silently failing.
TD1 “permission denied” dialog loop was fixed to stop repeated popups.
A monitor sleep/wake crash path was fixed by keeping offscreen surface handling on the GUI thread.
Color Match LUT access was made render-thread safe with a lock-free snapshot path.
Mask-toggle paths now include stronger bounds checks to prevent heap corruption in edge cases.
Help/readability issues across dark/light OS themes were fixed.
HugeForge/FlatForge fill-height mismatches were corrected so tiled outputs are consistent.
Also the HugeForge/ColorDrop/FlatForge path produces consistent height tiles.
FlatForge tiles have even fewer gaps than before. Still some issues but cleaner than they were.
ColorDrop/FlatForge was dropping layers with duplicate filament names.
Config Wizard now blocks invalid configuration moves into the app directory.
macOS startup was stabilized further by hardening early-init paths.
Love this software more than my kids lol. However I cannot seem to get 0.9.3.1 to boot at all. I can still use the old versions fine, but this one has got me a little stumped. Do you know of any issues like this on the Windows version? I have already attempted it while forcing my GPU into high performance while using the software.
When I try to run it in any capacity, it simply shows a loading icon for a few seconds, but then nothing ever happens.
I updated the software. That worked. But Flat Huege is no longer working. The plugin was correctly integrated. The DLL is located where it should be, but Hueforge no longer displays the plugin. When I try to reinstall it, it says it's already installed. Nevertheless, it's not showing up in the plugin tab.
