Version 1.6.12

Highlights

  • OBJ file support — 3D previews and thumbnails now work for .obj models
  • Dramatically lower memory use when previewing large models, fixing a crash some users hit
  • Faster search in large libraries
  • Filter your library by specific file extensions from the Types dropdown
  • Build plates now warn you before adding files that may not fit — with an Undo on the confirmation

What's New

Library

  • .obj files now render 3D previews and thumbnails, just like STLs
  • New File Types section in the Types filter dropdown — filter by any specific extension (.stl, .obj, .png, …), with search built into the menu
  • The thumbnail picker now shows hover-activated 3D previews, and the file/thumbnail picker dialogs open larger by default

Printing

  • Adding files to a build plate now runs a fit check first — if everything may not fit, you'll see a warning with plate fullness and an Add Anyway option
  • The "Files Added!" confirmation now includes an Undo button to reverse the add in one click

Improvements

Performance

  • Large model previews use far less memory — models are now loaded with streaming and vertex welding, cutting memory for a 9-million-triangle model from ~1.8 GB to ~0.6 GB
  • The app now proactively frees memory after closing large 3D previews
  • Faster search in large libraries

Library

  • Folder thumbnails no longer crop non-square images — landscape images picked via the thumbnail picker now display fully
  • Closing the window with X now exits the app by default on new installs (previously minimized to tray; existing installs keep their current setting)

Bug Fixes

  • Fixed a crash that could occur when hovering over very large models — caused by memory spikes during 3D preview loading
  • Fixed the detail panel loading the same 3D model twice behind the scenes, wasting memory and GPU time
  • Fixed files pasted into the library during an in-app import being permanently lost by the folder watcher — they're now picked up once the operation finishes
  • Fixed archives added while the app was closed not being detected at the next launch — startup scanning now handles them like the live watcher (honoring your auto-extract setting)
