Hi. I am here today to report two errors:
Under the “What is with this coordinate system? Which way is up?” heading,
this section correctly states that both Unity and UE4 use a left-handed coordinate system.
However, it incorrectly states that in UE4, “positive Y is “right””.
In reality, in UE4, positive Y is left.
Under the “Unity3D” heading, this section correctly states that “Unity uses a left-handed coordinate system”
However, under the “Unreal Engine4” heading, it incorrectly states that
“Unity uses a right-handed coordinate system”
Instead, it should say that
“Unreal 4 uses a left-handed coordinate system – where the vertical direction is usually represented by the +Z axis.”
This section is correct about the Y-axis though … it says “Y - left, right” (correctly implying that left is positive)
Thanks and good luck,
