Fixed Issues
| General |
|---|
| Loading files with a large number of cameras no longer causes Alias to freeze when Keep Windows and Keep Cameras is turned off in Open File options. ALS-29917 |
| Pressing the space bar now allows you to confirm with default responses in several confirmation windows. ALS-29585 |
| Look At: Fixed an issue where the Look At option behaved differently on stitched geometry. ALS-27429 |
| Fixed a launch failure caused by special characters in Windows account names when using Polish language settings. Alias now supports multi-byte characters in these scenarios. See Multi-byte Character Support. ALS-25678 |
| Fixed display and save issues involving special characters in file names and user accounts. ALS-27901 |
| Fixed the plugin Search Path functionality so plug-ins now appear correctly in Plug-in Manager. Note that after changing the Plugin Search Path preference, you need to restart Alias for the changes to take effect. ALS-31297 |
| Fixed an issue where Automotive Assets 2025 failed to install after completing AliasStudio 2025.1 installation. This occurred on clean Windows 10 environments and affected Alias AutoStudio versions 2023 to 2025.1. ALS-31755 |
| Fixed an issue where clicking the Non-Proportional Scale icon in the ViewCube options caused the view to jump unexpectedly. ALS-31757 |
| Corrected the behavior of the minute (mm) option in the Increment and Save Setting, which previously displayed the current month instead of minutes. ALS-32582 |
| Fixed an issue where Auto Hide did not function properly when undocked windows were stacked on top of each other. ALS-27760 |
| Alias no longer crashes when switching to the VRED Renderer on systems with AMD graphic cards. ALS-31685 |
| Improved performance for large files especially when copying and pasting. ALS-31462 |
| UI |
|---|
| Floating window groups: Selecting Help and Resize to Fit now work as expected for floating groups and tabbed floating groups. When the windows are a tabbed floating group, selecting Help accesses the help topic for the active tab. When windows are a non-tabbed floating group, selecting Help accesses the help topic for the left-most window in the group. ALS-30644 |
| Floating window group: Fixed an issue where double-clicking the title bar did not collapse the group as expected. ALS-30642 |
| Stretch Curve and Transform Curve tools: Improved handle selection accuracy. ALS-28972 |

Known Issues
Systems with NVIDIA graphics cards using driver version 32.0.15.8097 may experience Alias crashes or freezing with repeated resizing of windows.
Workaround: Ensure that your NVIDIA drivers are up to date.
Previously accessed or executed menu items are not highlighted when reopening the menu.
Alias may crash when using Undo after performing a Subdiv Cut operation. This issue can occur in workflows that include retopologized subdiv geometry with symmetry and bridging.
Workaround: Avoid using Undo immediately after a Subdiv Cut operation in these scenarios.
In the Variant Lister, the progress wheel may remain visible after quickly toggling between Variants. The scene remains interactive, but the wheel does not disappear until the session is restarted.
Alias Dynamo: When working in the graph (Node View), if you select the end of a node and drag out a wire to connect it to a different node, the wire disappears when you press the middle mouse button to pan the view.
Alias Dynamo: When performing Save As in Node View, input information may be lost.
Animation Playback: Outputting images with resolutions greater than 1500 pixels may cause your system to run out of memory.
Shader Lister: Modifying a linked shader using Assets > Modify from the More menu does not correctly update in the user interface
Workaround: Close and reopen the Shader Editor to refresh the user interface. Alternately, select the link icon in the Shader Editor and select Modify.
