Mirror Enhancements (2024.1)
We've added a new Keep Surface Normals option, which lets you control the normal orientation when mirroring geometry. The new option provides the behaviors from pre-2022 versions of Alias and Alias 2023.
Keep Surface Normals - off
This is the behavior from pre-2022 versions of Alias.
The resulting UV directions allow for mirrored behavior when using Transform CV > Slide on both surfaces.
The disadvantage is that the geometric normals are flipped. These can be modified later using Set Geometric Surface Orientation.
Keep Surface Normals - on
This is the behavior introduced in Alias 2023 (if the default setting of Swap UV is used in 2024.1).
This maintains the geometric normal direction, which is often preferred for exporting geometry. However, using Transform CV > Slide does not produce mirrored results on the two surfaces.
