Camera Lag doesn't work with `AutoCalculateOrthoPlanes`?

[huyqpham]

My camera lag (with Orthographic type) worked normally until I change to use the AutoCalculateOrthoPlanes.

My camera component settings:

• Camera type: Orthographic
• AutoCalculateOrthoPlanes: true
  My spring arm settings:
• Enable Camera Lag: true
• Draw Debug Lag Markers: true (And I can see the marker still work)

How to fix this?

I fixed this. Here is my solution:

// [5.4.0] Engine/Source/Runtime/Engine/Private/Camera/CameraStackTypes.cpp
// ... add those lines after the line 431
FVector TranslationView = RotMat.GetColumn(3);
TranslationView.Normalize();
InOutProjectionData.CameraToViewTarget = CameraToViewTarget * TranslationView;
return true;
