In UE 5.6, the Top View (Orthographic XY) axis orientation was changed by modifying
the Roll value from 0.0f to -90.0f in EditorViewportClient.cpp:
UE 5.5: FRotator(-90.0f, -90.0f, 0.0f)
UE 5.6: FRotator(-90.0f, -90.0f, -90.0f)
This causes the X-axis to appear vertically instead of horizontally in the Top View,
which breaks established workflows for many users working with GIS data,
architectural projects, and urban planning applications.
Request:
1. Revert to the previous behavior (UE 5.5 style), OR
2. Add an Editor Preference option like "Use Legacy Orthographic View Orientation"
to allow users to choose their preferred axis orientation.
This change significantly impacts productivity for projects that rely on
standard cartographic conventions (X = East, Y = North).
Thank you.
