Highlights 🎉
- Performance : Slicing is fast again — major slowdowns from 7.4 are gone.
- Stability : Fixed Error 2049 across the Library, crashes with Holes, and File Not Found errors.
- Workflow polish : Better Copy & Paste, multi-selection, plate handling, and support profile imports.
- Magic improvements : Now runs directly on the selected object, for finer control.
- Export clarity : Plate names now included in sliced files, for easier identification.
New ⚙️
- Shortcuts : `Ctrl + Shift + A` now also selects supports on the active plate.
- Plate Names in Sliced : Exported slices now embed the plate name for better tracking across multi-plate projects.
- Magic by Selection: now applies only to the selected object when multiple objects are present, instead of defaulting to all.
- Multi-Selection: Move To now works with multiple selected objects.
- Support Profiles : Scrollbar added to make importing easier with long lists.
Fixed 🐞
- Critical Errors & Crashes :
- Error 2049 in the Library no longer occurs.
- Resolved slicing slowdown introduced in 7.4.
- Fixed crashes when applying “Holes Only / Cap Only / Holes + Caps” to multiple objects
- Copy & Paste :
- Paste option now visible even if no object selected
- No more “File Not Found” errors after pasting
- Copying resin objects with supports into FDM scenes now correctly imports supports
- Hollowing preserved when copying models
- UI/UX Issues :
- Using Holes Only on a moved hollowed object no longer turns it red or reassigns it to the wrong plate.
- The hide/show icon is now correctly disabled when only one plate exists.
- Fixed an issue where the printer shape or plate outline was incorrectly displayed in Banana Scale mode
- Fixed issues with where mouse rotation + zoom combinations at the same time was not working
- Fixed an issue where pasted objects turned solid red instead of striped when moved outside a plate.
- Fixed an issue where using Shift + rectangle selection caused multi-selection to flicker and toggle objects incorrectly.
- Freespin + Shift mouse wheel no longer breaks the UI.
- Fixed an issue where hidden plate controls (Add Plate / plate selection) were still accessible in Single Feature and Export (At Scale) menus
- Export/Import :
- Fixed an issue where objects sent to Outside could incorrectly appear on other plates (e.g., plates 7 and 8) after merge or copy/paste with more than 8 plates.
- Fixed an issue where exporting to STL/OBJ triggered an unnecessary alert about hidden models not being exported
- Supports :
- Copy/Paste of resin support parameters now respects all settings including “Mini” toggle
- Batch mode now consistently applies selected supports instead of always Medium supports.
- Fixed an issue where generating automatic supports on some models (e.g., Elegoo Saturn 3 Ultra) caused Lychee to hang when adding bracings.
