What's Changed

  • Limit visibility of custom filament profiles based on OrcaFilamentLibrary to currently selected printer only by @SoftFever in github.com/SoftFever/OrcaSlicer/pull/8779 ↗ — With the newly introduced Global Filament Library in 2.3.0, when users save custom filament profiles, if the base profile is from the Orca Filament Library, these user profiles will automatically become visible to all printers, which can be annoying. — To address this, we now ensure that new user profiles derived from system profiles (from the Orca Filament Library) are automatically set to be visible only to the selected printer model. — Users can also manually adjust the compatibility of filament profiles in the filament settings if they want.
  • QoL: Add auto perspective by @Noisyfox in github.com/SoftFever/OrcaSlicer/pull/8312 ↗ — This new QoL feature introduces auto perspective that works similar to Blender:
  • When click the top/bottom/left/right/front/back on the 3D navigator, or switch to those view from the menu, or by shortcuts (Ctrl+1-6), the camera automatically switch to orthogonal view
  • When switch to any other angles, either by dragging with mouse/track pad, or by clicking other non-perpendicular faces on 3D navigator, or select default view from menu/short cut (Ctrl+0), the camera automatically switch to perspective view
  • Panning and scalling won't trigger the view change
  • This is optional and disabled by default, you can enable this from the view menu — image

This new feature also fixes a few issues with 3D navigator:

  • When click top/bottom view, sometimes the orientation is wrong. Now the orientation is always the same as if you select the top/bottom view from the view menu or by the shortcut.
  • When dragging the 3d navigator vertically, once the vertical limit is reached and you keep dragging it, the view will keep fliping diagonally (gimbal lock, techenically). This issue is illustrated as below, and has been fixed in this PR and the orientation is stable. flipping
